Airstrikes by a US-led coalition on territory held by the Islamic State (IS) have resulted in the deaths of at least 56 civilians on Tuesday according to Syrian opposition activists.
The villages of Tokhar and Hoshariyeh in the IS stronghold of Manbij has been the subject of an offensive by Kurdish militants backed by a US-led coalition for several weeks, reports the New York Times.
The Syrian Observatory for Human Rights stated at least 56 civilians, including 11 children, were killed in the strikes, whilst IS linked media claims the number is as high as 160.
Meanwhile Amnesty International claimed that more than 100 civilians have been killed in airstrikes around Manbij since June.
"There must be a prompt, independent and transparent investigation to determine what happened, who was responsible, and how to avoid further needless loss of civilian life," said Magdalena Mughrabi, interim Deputy Director of the Middle East and North Africa Programme at Amnesty International.
"Anyone responsible for violations of international humanitarian law must be brought to justice and victims and their families should receive full reparation".
