Dozens of civilians have died in two days of intense US-led strikes on Raqqa, a monitor said on Tuesday, as fighting to retake the Syrian city from jihadists nears its densely populated centre.
The US-backed Syrian Democratic Forces (SDF) have captured just under 60 per cent of Raqqa, monitors say, leaving jihadists from Islamic State in control of about 10 sq km in the heart of the city.
But as clashes approach central Raqqa, monitors and activists have reported scores killed in intensifying coalition bombardment of the city.
On Monday, US-led air strikes killed at least 42 civilians in several neighbourhoods in Raqqa under IS control, according to the Britain-based Syrian Observatory for Human Rights monitor.
Nineteen children and 12 women were among the dead.
That takes to 167 the number of civilians killed in coalition strikes since August 14, after the Observatory said at least 27 were killed on Sunday.
