At least 10 killed in northern Syria blast

At least 10 people have been killed when an Islamic State suicide bomber blew himself up in northern Syria.

At least 10 people have been killed when an Islamic State suicide bomber blew himself up in a village in northern Syria, the Syrian Observatory for Human Rights monitoring group says.

Tuesday's blast took place in al-Mashi, which is in the countryside around the city of Manbij and wounded another 20 people, it said. US-backed forces captured Manbij and its surrounding areas from Islamic State in August.

The jihadist group is launching attacks against those forces in the Manbij area, the British-based Observatory says.

Since the Manbij operation, a Kurdish contingent of the US-backed Syria Democratic Forces has withdrawn from the city, the Pentagon said last month, but non-Kurdish forces from the SDF-allied Manbij military council remained.

Turkey, which has fought against the Kurdish YPG militia in Syria, is supporting Syrian insurgents in a separate push against Islamic State further west of Manbij.

Al-Mashi is currently under the control of the Manbij Military Council, the Observatory said.
