Warships from Russia's Black Sea Fleet have taken up position off Crimea's western coastline to help strengthen the peninsula's air defenses in response to the start of Ukrainian missile tests nearby, the RIA news agency reported on Thursday.
Kyiv began two days of missile tests on Thursday, angering Russia, which has put its air defense forces on high alert saying it hopes the war games won't disrupt international flights.
"Warships of the Black Sea Fleet... have taken up positions near Crimea's western coast for the duration of Ukraine's planned missile tests from Dec. 1-2," a military source in Crimea told RIA.
"The ship's air defense units have been put on a higher state of alert. Their equipment is designed in the first instance to shoot down heavy anti-ship missiles and cruise missiles. Together with land-based air defense units on the peninsula, the ships have thrown up a practically impenetrable shield against the enemy's rockets."
Volodymyr Kryzhanivskyi, a Ukrainian military official, earlier on Thursday told the 112 TV channel that the exercises had begun and that everything was going smoothly.
"The tests are being carried out in accordance with international law," said Kryzhanivskyi. He said they were taking place at least 30 kilometers (18.64 miles) from Crimean air space. "Therefore it would be wrong to reproach Ukraine," he said.
Russia annexed Crimea from Ukraine in 2014.
