Six U.S. Air Force F-16 fighter jets and about 300 personnel arrived on Aug. 9 at the Incirlik Air Base in Turkey from a base in Italy to support Operation Inherent Resolve against the IS in Iraq and Syria.
The Pentagon on Wednesday announced that the U.S. had begun flying manned counter-IS missions from Incirlik Air Base and conducting airstrikes against IS targets.
This followed Turkey`s announcement in July that it would open its bases for U.S. and coalition members` air operations against IS, as part of deeper U.S.-Turkey counter-IS cooperation.
U.S. officials said Friday that the coalition forces continued airstrikes against IS targets in Syria and Iraq, including eight strikes in Syria and 23 strikes in Iraq that destroyed a number of IS fighting positions, vehicles and weapons.
