AIN AL-ASAD BASE, Iraq (AP) — U.S. troops were clearing rubble and debris on Monday from a military base housing American soldiers in western Iraq, days after it was struck by Iranian ballistic missiles. The Ain al-Asad air base in Iraq’s western Anbar province is a sprawling complex about 180 kilometers (110 miles) west of Baghdad and houses about 1,500 members of the U.S. military and the U.S.-led coalition fighting the Islamic State militant group. It was struck by a barrage of Iranian missiles on Wednesday, in retaliation for the U.S. drone strike that killed a top Iranian commander, Gen. Qassem Soleimani, whose killing raised fears of a wider war in the Middle East.
