“It’s high time the US authorities came clean about the full extent of the civilian damage caused by coalition attacks in Syria," Deputy Director for Research at Amnesty’s Middle East and North Africa Regional Office Lynn Maalouf said Tuesday; Press TV reported.

The UK-based rights group said as many as 300 civilians had been killed in 11 attacks conducted by the Washington-led alliance since September 2014.

“Analysis of available evidence suggests that in each of these cases, coalition forces failed to take adequate precautions to minimize harm to civilians and damage to civilian objects,” Maalouf added.

Amnesty further urged independent investigations into possible violations of international law, calling on the coalition to take more precautions prior to their attacks.

“Some of these attacks may constitute disproportionate or otherwise indiscriminate attacks,” Maalouf said.

2014 saw the rise of the Takfiri group of Daesh in the Arab country and neighboring Iraq.

Washington subsequently brought scores of its allies under the military umbrella to hit what it calls Daesh targets in the two Arab countries.

The campaign has fallen well short of eliminating the terrorists, raising questions as to the nature of the coalition’s military engagement.
