A new satellite image from Maxar Technology appears to show a missile strike Thursday near Snake Island, in southern Ukraine.
Two plumes of smoke are seen near to a Russian Serna-class landing ship in the Black Sea, identified by Maxar.
The ship appears to be making a sharp turn where the missile hits the water.
Near the island, a barge with a heavy-lift crane is seen next to another sunken vessel, which Maxar has also identified as a Serna-class landing ship.
It's unclear how the ship sank, but on Sunday, spokesman for Odesa region military administration Serhiy Bratchuk said that a landing boat was hit, in addition to two Raptor-class patrol boats.
Bratchuk also claimed the Ukrainian military had destroyed a Russian helicopter on the island. The Ukraine Armed Forces Southern Operational Command released video showing a helicopter being destroyed by a missile on Sunday.
In recent weeks, the Ukrainians have repeatedly — and successfully — destroyed Russian forces and vehicles on the island.
Bratchuk claimed on Thursday that a Russian support ship, the 'Vsevolod Bobrov' was on fire and being towed to Sevastopol from the area of Snake Island. That support ship is not seen in this satellite image, and the claim remains unverified by CNN.
So far Russia has not confirmed the loss of any of the ships mentioned.
