MOSCOW (AP) — The Russian military on Friday launched sweeping maneuvers in the Mediterranean Sea featuring warplanes armed with state-of-the-art hypersonic missiles, a show of force amid a surge in tensions following an incident with a British destroyer in the Black Sea.

Moscow said one of its warships fired warning shots and a warplane dropped bombs in the path of British destroyer Defender on Wednesday to force her out of an area near Crimea that Russia claims as its territorial waters. Britain denied that account, insisted its ship wasn’t fired upon and said she was sailing in Ukrainian waters.

The Russian drills that began Friday in the eastern Mediterranean come as a British carrier strike group is in the area. Earlier this week, British and U.S. F-35 fighters from HMS Queen Elizabeth flew combat sorties against the Islamic State group.

Russia has waged a military campaign in Syria since September 2015, allowing Syrian President Bashar Assad’s government to reclaim control over most of the country after a devastating civil war.

The Russian Defense Ministry said that a pair of MiG-31 fighter jets capable of carrying Kinzhal hypersonic missiles arrived at the Russian airbase in Syria and flew training missions to practice strikes on targets in the Mediterranean. The Hemeimeem airbase, in the coastal province of Latakia, serves as the main hub for Moscow’s operations in the country.

It's the first time the warplanes armed with Kinzhal have been deployed outside Russia's borders.

The military says the Kinzhal has a range of up to 2000 kilometers (about 1,250 miles) and flies at 10 times the speed of sound, making it hard to intercept.

The Defense Ministry said the maneuvers in the eastern Mediterranean also involve several warships, two submarines and long-range Tu-22M3 bombers along with other combat aircraft. The supersonic, nuclear-capable Tu-22M3s were first deployed to Syria last month in a demonstration of an increased Russian military foothold in the Mediterranean.

The Russian military has modernized the runway at Hemeimeem to accommodate heavy bombers and built a second one to expand the operations there.

Russia also has expanded and modified a naval base in the Syrian port of Tartus, the only such facility that Russia currently has outside the former Soviet Union.

The Russian military has increased the number and scope of its drills amid a bitter strain in relations with the West, which have sunk to post-Cold War lows after Moscow’s 2014 annexation of Ukraine’s Crimean Peninsula. As part of President Vladimir Putin’s efforts to beef up Russia’s military, the Russian navy in recent years has revived the Soviet-era practice of constantly rotating its warships in the Mediterranean.

Speaking to reporters Sunday aboard HMS Queen Elizabeth, Commodore Steve Moorhouse said the eastern Mediterranean has become more “congested and contested” with the heavier Russian military presence in Syria, resulting in regular encounters with Russian ships and warplanes. He noted that a Russian warship has come within 10 kilometers (16 miles) of the carrier.

In Wednesday's Black Sea incident, Britain insisted the Defender had been making a routine journey through an internationally recognized travel lane and remained in Ukrainian waters near Crimea. The U.K., like most of the world, recognizes Crimea as part of Ukraine despite the peninsula’s annexation by Russia.

Russia denounced the Defender's move as a provocation and warned that next time it could fire to hit intruding warships if they again try to test the Russian military's resolve.

Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov on Friday derided the British denials that the Russian military fired warning shots at the Defender and urged Britain and its allies not to “tempt fate” again. He added that the Defender is "just a juicy target for the Black Sea Fleet's missile systems.”
