AFP, Beirut :
Air strikes by the US-led coalition Saturday killed 43 people, mostly civilians, in a holdout of the Islamic State group in eastern Syria, a Britain-based monitor said.
Seventeen children were among 36 IS family members killed in Abu Husn village of Deir Ezzor province near the Iraqi border, the Syrian Observatory for Human Rights said.
Another seven victims had not yet been identified as either civilians or IS fighters, it said. The US-led coalition has been backing a Kurdish-Arab alliance called the Syrian Democratic Forces (SDF) fighting to expel the jihadists from the pocket around Abu Husn.
“It’s the highest death toll in coalition air strikes since the SDF launched its attack against the IS pocket” in September, Observatory chief Rami Abdel Rahman said.
The coalition has repeatedly said it does its utmost to prevent civilian casualties.
“The avoidance of civilian casualties is our highest priority when conducting strikes against legitimate military targets with precision munitions,” spokesman Sean Ryan told AFP this week. IS overran large swathes of Syria and neighbouring Iraq in 2014, proclaiming a “caliphate” in land it controlled.
But the jihadist group has since lost most of it to various offensives in both countries.
In Syria, the group has seen its presence reduced to parts of the vast Badia desert and the pocket in Deir Ezzor.
The coalition has since 2014 acknowledged direct responsibility for over 1,100 civilian deaths in Syria and Iraq, but rights groups put the number killed much higher.
Meanwhile, the US-led anti-jihadist coalition hit back Sunday at reports its air strikes on an Islamic State group holdout in eastern Syria had killed civilians, appearing to blame their deaths on regime forces.
More than seven years into the country’s civil war, multiple offensives have whittled down the swathes of Syrian territory IS once controlled to a small pocket in the eastern province of Deir Ezzor on the Iraqi border.
A Kurdish-led alliance backed by the coalition is battling to expel IS from that holdout, on the eastern bank of the Euphrates.
Russian-backed regime forces have been fighting the jihadists west of the river.
The Syrian Observatory for Human Rights said coalition strikes on Saturday killed 43 people, including 36 family members of IS fighters in the village of Abu al-Husn.
But the coalition denied that its air raids there had killed any non-combatants.
The US envoy for the coalition, Brett McGurk on Sunday appeared to blame regime forces stationed “across the river” for the civilian casualties.
