A Russian Navy vessel out on a science expedition was attacked and may have been sunk, not by an enemy ship, but by a walrus protecting its calves, officials say.
The joint expedition by Russia's Northern Fleet and Geographical Society was sailing in the Franz Josef Land archipelago in the Arctic Ocean last week when the incident occurred.
Russian military officials said in a statement that the vessel was attacked as researchers were making a landing at Cape Heller on Wilczek Land, an island on the archipelago.
"A group of researchers had to flee from a female walrus who attacked an expedition boat when protecting her cub," the Russian military statement reads, according to the Barents Observer, an English-language news site in the region.
