A US air strike killed nearly 60 civilians, including children, in Syria on Tuesday after the coalition mistook them for Islamic State fighters.

Some eight families were hit as they tried to flee fighting in their area, in one of the single deadliest strikes on civilians by the alliance since the start of its operations in the war-torn country. 

Pictures of the aftermath of the dawn strikes on the Isil-controlled village of Tokhar near Manbij in northern Syria showed the bodies of children as young as three under piles of rubble. 

The UK-based Syrian Observatory for Human Rights said the strikes appeared to have been carried out in error, with the civilians mistaken for Islamist militants.

It is thought Tuesday’s bombing was among the first by jets taking off from Incirlik air base in Turkey since it reopened after the failed coup.

The area has seen intense fighting between extremists and members of the US-backed Syria Democratic Forces (SDF) that have been advancing towards the Isil stronghold of Manbij under the cover of intense airstrikes by the US-led coalition.

The coalition has carried out more than 450 air strikes around the city since the operation to take the town began in May.

The SDF, an alliance of Kurdish and Arab fighters, is trying to seize the last territory held by Islamic State on the frontier with Turkey.
