Beirut: US-led coalition air strikes on two Syrian provinces targeting jihadists have killed 472 civilians over the past month, more than double a previous 30-day toll, the Syrian Observatory for Human Rights said on Friday.
The monitor said the period between 23 May and 23 June saw the highest civilian death toll in coalition raids for a single month since they began on 23 September, 2014.
Observatory head Rami Abdel Rahman said 222 civilians, including 84 children, were killed in the largely Islamic State group-held province of Deir Ezzor.
Another 250 civilians, including 53 children, were killed in Raqqa province, where US-backed forces are trying to oust Islamic State jihadists from their bastion Raqqa city.
He told AFP that the new deaths brought the overall civilian toll from the coalition's campaign to 1,953, including 456 children and 333 women.
The previous deadliest 30-day period was between 23 April and 23 May this year that cost 225 civilian lives.
The coalition insists it takes every measure to avoid hitting civilians, including by aborting missile strikes at the last moment if a civilian unexpectedly wanders into the target zone.
A total of more than 320,000 people have been killed since Syria's conflict erupted in 2011 with anti-government protests, according to the Britain-based Observatory.
