BEIRUT - A group monitoring the Syrian war said at least nine people including five children were killed in a Syrian army air strike on a school in a rebel-held area of the country's second city Aleppo on Sunday, though the army denied the report.
A Syrian army source told Reuters the army had stepped up attacks on rebels since the insurgents bombarded a government-held residential area in the northwestern city on Saturday. But he said the military was not targeting civilians.
Aleppo is a major frontline in the four-year-old Syrian civil war, a conflict which the United Nations says has killed around 220,000 people. The city, about 50 km (30 miles) from the Turkish border, is divided between government and insurgent control.
