A US-led coalition carried out at least 30 air strikes in Syria against Islamic State militants in the northern province of Raqqa on Saturday, a monitoring group said.
The Britain-based Syrian Observatory for Human Rights said the air strikes hit Islamic State positions in the northern outskirts of Raqqa city, a major stronghold of the hardline Islamist militants.
The areas hit by the strikes included the 17th Division, a Syrian army base that Islamic State seized in July, the Observatory said.
