The Ukrainian president calls for emergency session of his war cabinet after at least two sailors are injured in the strikes.
Ukraine says Russia has opened fire on its ships in the Black Sea and captured three vessels.
Two sailors have been wounded after two artillery boats were hit in the strikes, the Ukrainian navy said.
Ukrainian President Petro Poroshenko has called an emergency session of his war cabinet after a day of rising tensions off the coast of Crimea.
A statement from Ukraine’s ambassador to the UK said Russian special forces had captured three ships in an “act of aggression”.
“According to the Ukrainian navy, Russia opened fire at small-sized ‘Berdiansk’ and ‘Nikopol’ armoured artillery boats,” the statement said.
“The ‘Yany Kapu’ tugboat also lost ability to move following the Russian assault.
“Two Ukrainian crew members have been wounded. Russian special forces have captured all three Ukrainian ships.”
Ukrainian foreign ministry spokeswoman Mariana Betsa said: “Today’s dangerous events in the Azov Sea testify that a new front of Russian aggression is open.
“Ukraine is calling now for an emergency meeting of the United Nations Security Council.”
In response, Russia’s Federal Security Service (FSB) said it had “irrefutable evidence that Kiev prepared and orchestrated provocations… in the Black Sea”.
“These materials will soon be made public,” the FSB said.
