Up to five civilians died in an airstrike on the al Mrashda river crossing in Deir Ezzor, local media said – though sources were conflicted as to whether the US-led Coalition, Syrian regime or Russia were responsible.

According to Al Hall, the Coalition “targeted the water crossing in the town of Al Mrashda in rural Bu Kamal also, killing one man and three children and wounding four others, most of them in critical condition”.

The Syrian Observatory for Human Rights said that it was “unknown” whether the planes belonged to the Coalition.

However, Baladi said that Russia was. It said that five people died and others were wounded. Alaraby also pointed towards Moscow.

But the Syrian Network for Human Rights blamed the regime, putting the death toll at four.

A number of other sources didn’t identify the warplanes that carried out the attack.
