At least 27 people were killed on Wednesday after airstrikes struck a hospital in a rebel-held part of Syria’s largest city, Aleppo, the Syrian Observatory for Human Rights said. Among the casualties were three children and three doctors, one of whom was the city's last paediatrician. According to the war monitor, 84 civilians were killed in government airstrikes and 479 in rebel attacks, in the last six days, Reuters reported.

Witnesses said Al Quds field hospital was hit by a missile from a fighter jet, according to a CNN report, which placed the toll at 27. It is unclear whom the fighter jet belonged to. Government troops, backed by Russian airstrikes, have been carrying out a massive offensive in Aleppo in recent months. Fighting in the city intensified from April 22. The landmark ceasefire agreement that came into force on February 27 is “barely alive”, the United Nations said.
