It first attacked the Russian boat’s communication antennas.
Then it fired at the boat from very close range.
A video showed gunfire, an explosion, and smoke.
Ukraine says the Russian boat sank.
Russia has not officially confirmed that the battle happened.
Ukraine’s Navy claimed its Sargan 3000 sank a Russian unmanned surface vessel.
