There has been a dramatic rise in the number of civilians killed in the fight against the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) in Syria and Iraq.
Rights groups who monitor deaths of civilians in both countries have said dozens of people have been killed in recent weeks in three separate air strikes.
Most of those who died were in the Iraqi city of Mosul.
The US-led coalition on Saturday admitted to carrying out air raids last week at a location in west Mosul where scores of civilians were reportedly killed.
Several more were killed in northern Syria, when bombs were dropped on a school sheltering people and on a mosque. The US is investigating the incidents.
So, what is behind what appears to be an increase in the number of air raids against ISIL? And why has there been a sharp increase in the number of civilian deaths?
