A Syrian army air strike on an Islamic State-controlled town in northern Syria has killed at least 28 people including three children, a monitoring group said.
The Syrian Observatory for Human Rights, a UK-based organisation that monitors the war via a network of activists on the ground, said 19 civilians were among the dead in Saturday's helicopter attack on al-Bab, 30km northeast of Aleppo.
A US-led coalition is waging a separate campaign of air strikes against Islamic State targets in Syria, but rejects the idea of partnering with President Bashar al-Assad, who it sees as part of the problem.
