The U.S. military has deployed a dozen of A-10 ground-attack planes to the air base at Incirlik in southern Turkey, a U.S. official said on Tuesday, according to Agence France-Presse. The 12 planes, famed for their tank-destroying capabilities, arrived over the weekend and have already been scheduled to fly missions in support of the U.S.-led coalition fighting Islamic State jihadists in Iraq and Syria, the official told AFP.
