LONDON, Muharram 19, 1438, Oct 20, 2016, SPA -- Britain has deployed warships to monitor a Russian aircraft carrier group and other vessels Thursday as they sailed through the North Sea and the English Channel reportedly en route to Syria's coast, AP reported. The frigate HMS Richmond escorted the aircraft carrier Admiral Kuznetsov and its task group in the Norwegian Sea north of the U.K. between Iceland and Norway. The Type 45 destroyer HMS Duncan has sailed from Portsmouth to monitor the group as heads south toward the North Sea. The Royal Navy regularly shadows ships, and is being supported in this instance by the Royal Air Force. Russia is one the few countries which have the capability to deploy such a force — an aircraft carrier and supporting warships. "It's a clear and military signal that Russia is back on the international stage," said Peter Roberts, a senior research fellow for sea power and maritime studies at the Royal United Services Institute. The ships are sailing in international waters, so NATO forces such as those of Norway, the Netherlands and Britain will watch them go past without challenge. NATO Secretary General Jens Stoltenberg said alliance navies would monitor the Russian ships "in a responsible and measured way." "We are concerned that the Russian carrier group will support military operations in Syria in ways which will increase humanitarian and human suffering," Stoltenberg said in Brussels. -- SPA 22:39 LOCAL TIME 19:39 GMT www.spa.gov.sa/w
