Two people are missing and eight people were rescued after the attack made on a Ukrainian naval vessel by pro-Russian separatists in the Azov Sea, according to the representative of the Ukrainian border guard.

“A Ukrainian border patrol cutter in the Azov Sea was attacked from the shore today. Artillery was used. A rescue operation is under way,” said Ukrainian military spokesman Andriy Lysenko.

A Ukrainian military officer who requested not to be named said: “It appears that a ship has been damaged, I do not know who exactly fired on it and with what.”
