According the to Syrian Observatory for Human Rights (SOHR), US coalition air strikes killed at least 52 civilians, including seven children, and wounded dozens if others in the northern Syrian province of Aleppo on Friday.
US air raids also killed 7 armed men belonging to groups fighting against ISIS and Assad regime forces, according to the Daily Star.
Rami Abdulrahman, SOHR’s general director, said it appeared that the air raids struck civilians in a village on the eastern banks of the Euphrates River in Aleppo instead of ISIS targets.
Abdel Rahman said "not a single [ISIS] fighter was killed in the strikes on the village.”
"Air strikes by the coalition early on Friday on the village of Birmahle in Aleppo province killed 52 civilians," said Rami Abdel Rahman.
"Seven children were killed, and 13 people are still trapped in the rubble," he added.
Triggered by a bloody crackdown on peaceful protests in 2011 by the Assad regime - which has ruled the country for over four decades - the civil war in Syria has left the country in ruins.
So far more than 200.000 people have been killed and half the population has been displaced in the conflict.
More than four million Syrians have sought refuge in neighboring countries, with most of them going to Turkey, Lebanon, Jordan and Iraq.
