UN war crimes investigators say US-led coalition air strikes on Islamic State militants in the Syrian city of Raqqa are causing "staggering loss of life".

Hundreds of civilians are reported to have been killed since March, as coalition warplanes support an offensive by a Kurdish-led alliance.

The UK-based monitoring group Airwars estimates that more than 600 civilians were killed in more than 150 coalition or SDF attacks between March and May.

Air and artillery strikes killed dozens more in the first eight days of June, it says.

The UN Office for the Co-ordination of Humanitarian Affairs warned on Thursday that the assault was intensifying an "already desperate" situation in Raqqa.

Air strikes, shelling and clashes on the ground were killing and injuring civilians, and damaging key infrastructure, it said. There were also reports of increased shortages of essential commodities such as food, medicine and fuel, it added.
