A woman ran onto the red carpet at the Cannes Film Festival, to protest against sexual violence in Ukraine.
The protester stripped off a gown to reveal the words "stop raping us" painted on her body, along with the colours of the Ukrainian flag.
Ukrainian authorities have said they're investigating cases of women being raped by Russian forces during their occupation of parts of the country.

Russia steps up assault on Severodonetsk
Fierce fighting has been reported around the Ukrainian city of Severodonetsk as Russia steps up its attempt to capture the whole eastern region of Luhansk.
Local governor Serhiy Haidai said the Russians were "destroying" the city as they gradually surrounded it.
Writing on the messaging app Telegram, he said his troops had repelled 11 attacks on the frontline - with eight tanks among the Russian vehicles destroyed. There was no independent confirmation of the claims.
BBC correspondent James Waterhouse says Russia has increased its artillery and air strikes as well as missile attacks - gaining ground mile by mile in Luhansk while the Ukrainians are forced to retreat.
He says the Russians are "enjoying much more freedom of movement" as troops get redeployed following a successful siege of Mariupol.

Talks between Turkey, Finland and Sweden need to continue - Stoltenberg
Nato's Secretary General Jens Stoltenberg says he's spoken with Turkish President Recep Tayyip Erdogan about the importance of Nato’s open door following bids by Finland and Sweden to join the military alliance.
In return, Turkey's president told him that Ankara would not look positively on Sweden and Finland's applications, unless they clearly show cooperation in the fight against terrorism and other issues.
As we reported earlier, Erdogan held phone calls with the leaders of the two countries today to discuss his concerns.
Stoltenberg tweeted: "We agree that the security concerns of all allies must be taken into account and talks need to continue to find a solution.”

Ukraine's armed forces have given their usual evening update, as Russia continues its efforts to capture the remainder of the eastern Luhansk region. Here are some of the key takeaways:
The greatest Russian action was confirmed to be in what Ukraine calls its eastern operational zone
Ukrainian soldiers and civilians have come under fire in the Donetsk region, as Russian troops attempt to reach the borders of neighbouring Luhansk
The Russian forces were also observed preparing further offensives on Slovyansk and Lyman, both in the Donetsk region
Strikes were also acknowledged in northern areas, including in the Zhytomyr region, west of Kyiv - following a Russian claim it had destroyed a large shipment of donated weapons there
The BBC was not able to verify the claims.
