At least five people were killed and 12 wounded in an Isis attack in the Syrian border town of Jarablus, Turkish security and hospital sources said on Thursday, only a day after civilians started returning to their homes in the town.

Wounded people were taken to hospitals in Turkey's southern province of Gaziantep, which lies across the border from Jarablus, the same hospital sources said.

A group of 292 Syrians went back to the town from Turkey on Wednesday, marking the first formal return of civilians since Ankara launched a military incursion two weeks ago to try to secure the border region, a Turkish official said.

Jarablus, which had been held by Isis, was the first town captured by Turkey's army and its Syrian rebel allies in an offensive launched on 24 August that aims to sweep away jihadists and Syrian Kurdish militias from the frontier.

Turkey has said it cleared militants from a 55-mile stretch of Syrian territory and has pushed south. It has also said it would support any US initiative to strike Isis's stronghold of Raqqa, further to the southeast.

But Turkey's tactics have drawn criticism from its Nato ally the United States and also from Russia, with which it recently patched up ties.

Washington says Turkish attacks on Kurdish-aligned militias are damaging the US-backed coalition that is fighting Isis. Russia, which backs the government in Damascus, said on Wednesday Ankara's push south threatened Syria's sovereignty.
