Coalition forces led by the U.S. on Saturday carried out 30 or more air strikes against Islamic State of Iraq and Greater Syria (ISIS) militants in the northern Syrian province of Raqqa, said the U.K.-based Syrian Observatory for Human Rights.
The area under attack included a Syrian army base that ISIS fighters captured in July, Reuters reports.
At least 27 people were killed in a massacre in the province of Daraa on Monday, said the Observatory. Fighting also continues in the town of Kobani, which Kurdish fighters have been defending from an ISIS onslaught for over two months.
The U.S.-led coalition has bombed ISIS targets since September.
