More now on reports from Ukrainian officials that a Russian landing ship has been destroyed and two other boats damaged in the occupied Ukrainian port city of Berdyansk.
Video posted by the navy and on social media showed explosions and a big ship on fire at the port, about 70km (44 miles) west of Mariupol, at 07:00 local time (05:00 GMT) on Thursday.
The Ukrainian military said its forces had struck a Russian vessel called the Orsk.
Deputy Defence Minister Hanna Malyar later told Ukrainian TV that the military had hit a "huge target", capable of carrying 20 tanks, 45 armoured vehicles and 400 troops.
The BBC cannot independently verify the claim.
Russian army TV hailed the arrival of the Orsk in Berdyansk last week as an "epic event" as it was the first Russian warship to dock in Berdyansk.
Drone footage filmed by a Russian state TV reporter last week showed an armoured personnel carrier being offloaded from the Orsk in the port. The armoured vehicles were to be used to reinforce Russian troops, the TV report added.

Street after street, building after building, Mariupol lies in ruins
Hugo Bachega -BBC News, Lviv
A month into the war, there's destruction and suffering almost everywhere in this country. But no place has seen the horrors of Russia's unprovoked aggression like Mariupol.
The invading troops have surrounded the city and attacked it with no mercy, from air, land and, in recent days, also from the sea.
Almost nothing seems to have been left untouched. Street after street, building after building, the city lies in ruins.
And amid those ruins, 100,000 people are still trapped, subjected to a medieval-like siege.
There is no electricity, no gas, no running water. Some have melted snow to drink. Reports say children have died from dehydration.
Bodies are being left in the streets, as it's too dangerous for people to go out and get them. When they're finally collected, some end up buried in mass graves.
Ukrainian forces are fighting hard to keep this city in their hands. The fear, in Mariupol and elsewhere, is that if the Russians can't have it, they will do everything to destroy it.
