WOn 16 March 2017, an airstrike by the United States Armed Forces killed up to 49 people in the rebel-held village of al-Jinah near Aleppo, Syria. The US military claimed the people targeted in the strike were militants belonging to the terrorist group al-Qaeda. However, the Syrian Observatory for Human Rights (SOHR), local residents and local officials have claimed that the building struck was a mosque filled with worshipers. At the time, US military claimed that the structure bombed was not a mosque itself but was next to a mosque, which was undamaged. However, on May 5, 2017, a US Central Command investigation determined that the building was indeed part of a mosque-complex. Rami Abdel Rahman, head of SOHR, claimed the structure was a mosque which held over 300 people at the time of the strike. In September 2017, the United Nations Commission of Inquiry on Syria concluded that "United States forces failed to take all feasible precautions to avoid or minimize incidental loss of civilian life, injury to civilians and damage to civilian objects, in violation of international humanitarian law." The UN commission's findings did not support the U.S. claim that an al-Qaeda meeting was taking place.
