AMMAN (Reuters) - Eighteen foreign fighters from the Islamic State, including an American jihadist, were killed in a Syrian air raid on a town near the militant group's main stronghold city of Raqqa in eastern Syria, a human rights monitoring group said on Thursday.
The Syrian Observatory for Human Rights, which has tracked violence on all sides of the three-year-old conflict, said reliable sources reported that top Islamic State leaders who happened to be in the municipal building of Gharbiya at the time of the raid were among the foreign fighters killed.
