The United States carried out an air strike on Wednesday against Islamic State targets in the vicinity of the Syrian city of Aleppo, a U.S. official said, adding that the U.S. military would keep flying even as Russia starts rival operations.
U.S. officials, speaking on condition of anonymity, have told Reuters that Russia earlier on Wednesday told the United States to clear the skies in Syria about an hour before starting its own air strikes in the vicinity of the Syrian city of Homs.
