Mayor says Russians killed 320 civilians in Bucha
The mayor of the city of Bucha has told the BBC that some 320 civilians were shot dead by Russian troops during their occupation of the town.
Speaking on the Word Tonight, Anatoly Fedoruk said he had personally witnessed the executions of several people by Moscow's forces.
"I saw several episodes," Fedoruk said. "There were three civilian cars trying to evacuate themselves towards Kyiv and they were brutally shot. There was a pregnant woman whose husband was screaming asking not to shoot her but they just brutally shot her."
Fedoruk also alleged that Russian forces had been hunting local politicians during their occupation.
He called on Russian Foreign Minister Sergei Lavrov, who has denied allegations of war crimes by Moscow's troops, to "come over to the town of Bucha and to see the bodies of the dead people and to look into the eyes their families, mothers, husbands, kids who became orphans".
YouTube suspends channel of Chinese vlogger reporting on Ukraine
YouTube has suspended the account of a Chinese vlogger reporting on the Russian invasion of Ukraine.
Wang Jixian, a resident of Odesa for the past four years, said he had been posting videos of the Russian invasion to counter China's narrative of what was happening in the country. He says he had received multiple messages not to "provoke" Beijing.
China has been making concerted efforts to stifle strong views about the conflict in the country and has refrained from condemning Russia so far.
"I'm countering lies and panic by reporting from the front line," Wang told Radio Free Asia.
He says his YouTube account was suspended for posting "violent content" in a video from 28 March. Wang says his appeal against the suspension was ignored by the platform.
The BBC was able to confirm that although the channel is up, Wang is unable to post new videos.
Chinese censors have also cracked down on Wang's videos on the messaging app WeChat and Douyin, the country's version of TikTok.
Wang's Chinese social media accounts were previously banned after he spoke to CNN.

India supports Bucha killings probe in rare Russia condemnation
India said it “unequivocally condemned” the killings in Bucha and supported the call for an independent investigation into the "deeply disturbing reports".
The images of mass graves and bodies of civilians apparently executed in public places are the most shocking to emerge from Ukraine.
India's condemnation at the UN Security Council meeting on Tuesday is the country's strongest statement on Ukraine and Russia since the war began.
India has so far abstained from voting on resolutions at the UN Security Council, the UN General Assembly and at the UN Human Rights Council condemning Russian actions.
The country has a long history of pursuing a non-aligned strategy in international politics.
But its diplomatic balancing act is under pressure from Western countries to help rein in Russia.
India, which depends on Russia for oil imports, was criticised by the US and Australia last week for considering a Russian proposal that undermines Western sanctions.

Russia focused on controlling Donetsk and Luhansk - Ukraine army
Russian forces have focused their main efforts on an "aggressive" operation aimed at establishing complete control over the Donetsk and Luhansk regions, the General Staff of the Ukraine Armed Forces has said in its daily update.
There have also been continuous attacks in the eastern areas of the country, but without success, the update added.
It said Russian forces are also continuing their efforts to storm Mariupol, one of the most heavily bombed and damaged cities in Ukraine. Ukrainian troops had been fending off attacks on the city for over forty days.
It also alleged that Russia is continuing to actively use ammunition banned by international law.
The BBC has been unable to independently verify this.

Humanitarian situation worsening in Mariupol: UK MoD
Heavy fighting and Russian airstrikes have continued on the port city of Mariupol, according to the latest intelligence update from the UK's Ministry of Defence.
UK intelligence said the humanitarian situation in the city was "worsening".
"Most of the city’s 160,000 residents have no light, communication, medicine, heat or water. Russian forces have prevented humanitarian access, likely to pressure defenders to surrender," its latest statement said.
Mariupol has been encircled by Russian forces since the beginning of March. The Ukraine army said earlier today that its troops had been fending off attacks on the city for more than 40 days.
Last week, the International Committee of the Red Cross said it was forced to postpone an attempt to evacuate civilians from the besieged city after conditions made it impossible to proceed.
Life for civilians in Mariupol has been grim. Endless bombardments have left widespread destruction and the city's deputy mayor says people are dying from starvation and dehydration.
Russian forces have been advancing further into the centre of the city, but Ukrainian forces are still in control of some areas.

Hospitals bombed in Mykolaiv, says MSF chief
The international humanitarian charity Médecins Sans Frontières (MSF) says hospitals, patients and medical staff must absolutely be spared from attack in Ukraine.
The call comes after the head of MSF's mission in Ukraine, Michel-Olivier Lacharité, told the BBC's Newsday programme that three hospitals were hit in the Black Sea port of Mykolaiv in the past two days.
He says the hospitals are in residential areas and he believes they may have been hit with cluster bombs.
"At the moment of the explosion there [was] a gas leak and smell. So our team tried to escape from the scene", he says.
"While they were escaping they saw dead bodies on the road and people wounded."

Thousands of people who live in the Donbas in eastern Ukraine are fleeing west.
We passed a 50-mile tailback of traffic as we headed in the opposite direction - towards the fighting.
This is where Russia is stepping up its offensive, having withdrawn forces from the north.
Ukrainian troops are at check points on all roads in and out of the region.
They’re also preparing defensive positions, with some of Ukraine’s most experienced troops in the area.
It’s where they’ve been fighting Russian-backed separatists for the past eight years.
Russian forces now occupy most of Luhansk and more than half of Donetsk. They’re slowly trying to surround Ukrainian forces.

At least 167 children have been killed in Ukraine and 279 wounded in the Russian invasion, Ukrainian officials say.
Some 927 schools and other educational buildings have been damaged in shelling and bombardment, the Ukrainian prosecutor-general's office added in a message on Telegram this morning.
The biggest number of child casualties (81) was registered in the Donetsk region of eastern Ukraine, followed by the wider region of Kyiv (78) and the Kharkiv region (64).
The BBC cannot independently verify these figures.

What's the EU's latest plan to sanction Russia?
European Union ambassadors are meeting today to decide whether to impose fresh sanctions on Russia.
Calls in the West for new measures to damage the Russian economy have intensified following allegations of war crimes in Ukraine. Moscow denies that its forces have committed atrocities.
Yesterday, European Commission head Ursula von der Leyen set out a list of proposals, including:
A ban on EU nations importing Russian coal worth €4bn (£3.3bn) a year, and a full ban on four top Russian banks
A ban on Russian ships entering EU ports (with some exemptions) and on Russian road transport operators
Bans on EU exports of some tech and machinery including advanced semiconductors, and on imports on Russian alcohol, seafood, and wood
A restriction on Russian companies competing for contracts across the EU
The EU was also working on other sanctions including on imports of Russian oil, von der Leyen said.
Fuel bans have so far proven a sticking point, with countries including Germany heavily reliant on buying from Russia.

Five humanitarian corridors planned in eastern region of Luhansk
Ukrainian authorities in the Luhansk region hope to evacuate civilians through five humanitarian corridors on Wednesday, ahead of a feared Russian offensive in the east, Reuters reports.
"We will take everyone out if the Russians allow us to get to the meeting places [for evacuation]. Because, as you can see, they don't always observe ceasefires," the Luhansk region governor Serhiy Gaidai writes on Telegram.
"I appeal to every resident of the Luhansk region – evacuate while it is safe... While there are buses and trains – take this opportunity."
In a separate video address, Gaidai says Russian forces haven't managed to break through Ukrainian defences in his region but are destroying "everything in their path".

More than 400 people missing from Hostomel, say local officials
Ukrainian officials say more than 400 people are missing from the town of Hostomel which, along with Bucha and Irpin, bore the brunt of Russia's offensive on Ukraine's capital Kyiv.
Local official Taras Dumenko says most of the bodies of Hostomel's residents were found in neighbouring villages and the town of Bucha.
He says the Russians must have abducted people and taken them away, many of them to be shot, reports the Interfax Ukraine news agency.

In eastern Ukraine, some don't blame Putin for the war

Image caption: We're very near the front line in this part of the Donbas
Thousands of people who live in the Donbas in eastern Ukraine are fleeing west, as Russia is stepping up its offensive.
There are still some signs of life in the villages, towns and cities we travel through in this region of eastern Ukraine - but they're quickly emptying out.
We visited the town of Lysychansk, about a mile from the front line. It's one of many residential areas to have been hit by Russian artillery over the past few days.
Shattered glass and blocks of concrete lay strewn across the streets, along with the twisted steel remnants of the shelling. We could still hear the occasional rumble of artillery in the distance.
A Ukrainian soldier led us through the mostly-deserted streets to an underground shelter.
Inside in a gloomy room we talked to two old women, who were trying to keep warm in front of an electric fire.
We asked them who they thought was responsible for shelling their town - astonishingly, neither blamed Russia or President Vladimir Putin. They thought their grim situation was as much the fault of Ukraine and President Volodymyr Zelensky.
The women, who'd grown up in the Soviet era, seemed to share Putin's nostalgia for the past.
Our translator explained they'd probably watched and believed what they'd seen and heard from Russian state media.
This wasn't the view of everyone we spoke to, but it highlights the closer ties eastern Ukraine has to Russia - as well as a generational divide.

More detail on humanitarian corridors from Luhansk
Ukraine's deputy prime minister has said in online comments that she's aiming for 11 humanitarian corridors to open today to help evacuate civilians, Reuters reports.
Five of these corridors are to get people to safety from the region of Luhansk, in eastern Ukraine, ahead of an expected Russian offensive.
The corridors will take civilians west from Sievierodonetsk, Lysychansk, Popasna, Rubizhne and Hirske to the town of Bakhmut, Ukrainian news site Ukrinform says.
Deputy PM Iryna Vereshchuk said on her Telegram channel that 3,846 people were evacuated yesterday including 1,080 people from the Luhansk region.

Pope Francis condemned the "massacre of Bucha" and kissed a Ukrainian flag he said was sent to him from the town during his weekly audience at the Vatican's auditorium.
"Recent news from the war in Ukraine, instead of bringing relief and hope, brought new atrocities, such as the massacre of Bucha," Reuters quoted him as saying.
"Cruelty that is increasingly horrendous, even against civilians, defenceless women and children."
On Tuesday at the UN Security Council, Ukrainian President Volodymyr Zelensky accused the Russian military of carrying out the worst crimes since World War Two. The Kremlin has claimed there is no evidence Russian troops have carried out the atrocities they have been accused of.

Pope Francis unfolded a Ukrainian flag he said had been brought to him from Bucha and held it up for the audience, which broke into applause.
He then asked a group of children refugees who arrived on Tuesday from Ukraine to come up to him.
"These children had to flee in order to arrive in a safe land. This is the fruit of war. Let's not forget them and let's not forget the Ukrainian people," he said, before giving each child a gift of a chocolate Easter egg.

European Union leaders are facing growing pressure to sanction Russian energy exports following accusations its troops have carried out war crimes in Ukraine.
The EU Commission is proposing a ban on coal exports that'll be considered today as part of a wide-ranging fifth package of sanctions.
But the head of the European Council, Charles Michel, has told the European Parliament he thinks "measures on oil and even gas will also be needed sooner or later".
Other Western allies, including the United States and Britain, are expected to impose additional sanctions on Russia today.

Twenty-five women and girls have said they were raped by Russian forces in Bucha, a senior Ukrainian official has told the BBC.
Lyudmyla Denisova, the Ukrainian Parliament's Human Rights Commissioner, said a telephone helpline offering support had received at least 25 reports of rape of women and girls aged between 14 and 24 by Russian soldiers.
She said Ukraine had evidence of "genocide of Ukrainian people" and of military crimes, adding that rape was "the new weapon" of Russian forces.
Denisova added: "Together there were 25 women aged 14-24 that were raped by Russian soldiers.
"That was happening for a month. We will keep documenting these terrible crimes, unfortunately, and every criminal will be punished."
Russia has denied carrying out atrocities in Bucha.

Russian airstrikes continue on devastated Mariupol - city mayor
Hugo Bachega
BBC News, Lviv
The mayor of the besieged Ukrainian port of Mariupol, Vadym Boychenko, says the humanitarian condition in the city is "terrible", and that Russian airstrikes have continued almost non-stop.
Boychenko has told the BBC that Russia launched more than 100 missiles on Tuesday alone.
The BBC cannot independently verify the claim as communication with the city is extremely difficult.
The mayor is no longer in the city, which has been surrounded by Russian troops for more than a month, and receives updates from remaining residents.
Pictures from Mariupol show a city devastated, with the city council estimating that 90% of buildings have been damaged or destroyed, a third of them beyond repair.
Boychenko estimated that at least 120,000 residents remain in Mariupol. Attempts by the Red Cross to allow the safe evacuation of civilians have failed in recent days.
"It's a real hell that Russia created in my city," Boychenko says. "They are war criminals and must be punished for what they’ve done. But all we have to do now is to safely evacuate people from the city".
The latest assessment by the UK Ministry of Defence says heavy fighting and Russian airstrikes have continued, and that the situation for civilians is worsening.

We're on the outskirts of the town of Zaporizhzhia in south-east Ukraine, heading back into the centre as we've heard a Red Cross humanitarian escort is due to arrive.
I've just been at a dormitory housing dozens of families who have escaped the besieged port city of Mariupol and other towns in the region.
A mother of five young children, Liudmyla, is sharing a small room with another family.
They managed to get out of the town of Huliaipole, which she says has been flattened by Russian bombardment.
The children told me they were terrified. They have been hearing the sound of shelling and explosions and they saw Russian tanks and soldiers at the end of their street. They spent three days in the basement, with food and provisions running out.
It's a story I’m hearing over and over again as more families manage to make it north from Mariupol and the areas nearby.
There are thought to be hundreds of people on the Red Cross convoy heading into Zaporizhzhia.
They had made their own way to a town near Mariupol as the aid team still can't access the city.

What's the latest on Nato talks?
Paul Adams
BBC diplomatic correspondent
As Nato foreign ministers gather in Brussels, the next phase of Russia’s war in Ukraine is very much on their minds.
Nato’s Secretary General Jens Stoltenberg thinks it will be some weeks before Russia's ready to launch its next big offensive in the Donbas.
Troops and equipment have only just been withdrawn from the area around Kyiv and will take time to be resupplied and relocated to the east.
Other forces including foreign fighters, mercenaries and conscripts are being added to the mix.
But when the offensive comes, Nato officials warn that it will be “horrendous and barbaric”.
They believe Russian President Vladimir Putin would like to be able to declare some kind of victory, however limited, by 9 May when Russia holds its annual Victory Day parade, marking the defeat of Nazi Germany at the end of the Second World War.
Nato members are determined to use the coming days and weeks to make sure Ukraine is as ready as it can be, and deny the Kremlin anything to celebrate.

No indication that Putin has changed his ambition - Nato
Nato's secretary general Jens Stoltenberg is just speaking in Brussels, where foreign ministers from the security alliance are gathering this afternoon.
"We have seen no indication that President Putin has changed his ambition to control the whole of Ukraine and rewrite the international order," he says.
The secretary general says that Nato needs to support Ukraine, sustain the sanctions on Russia and strengthen its own defences and deterrents.
He says the conflict may last a long time "and we need to be prepared for that".
