TAMPA, Fla., Sept. 23 (UPI) -- Airstrikes in Syria by the United States and five Arab countries in the region targeted the Islamic State and the al-Qaida-aligned Khorasan.
The heavy concentration of bombs, launched from the air and sea, centered on the defacto IS headquarters in the Syrian city of Raqqa, as well as bases, checkpoints and training centers of the militant Islamic group in at least four Syrian provinces, U.S. military officials said.
