US-led coalition air strikes killed at least 42 civilians after targeting densely-populated neighborhoods of the ISIS-controlled Syrian city of Raqqa, a monitoring group has said.
The Britain-based Syrian Observatory for Human Rights said the dead included 19 children and 12 women.
The activist-run group Raqqa Is Being Slaughtered Silently said 32 people were killed in air strikes on one neighborhood alone.
The US Central Command (CENTCOM) said its civilian casualty team would assess the allegations.
“The Coalition takes all allegations of civilian casualties seriously and assesses all credible allegations of possible civilian casualties. Coalition forces work diligently and deliberately to be precise in our airstrikes,” spokesperson for CENTCOM told reporters.
