At least 544 civilians killed in Russian-led assault in Syria, rights groups say

Syrian Network for Human Rights says two-month offensive has left 130 children dead

At least 544 civilians have been killed and over 2,000 people injured since a Russian-led assault on the last rebel bastion in north-western Syria began two months ago, according to rights groups and rescuers.

Russian jets joined the Syrian army on 26 April in the biggest offensive against parts of rebel-held Idlib province and adjoining northern Hama provinces in the biggest escalation in the war between the Syrian president, Bashar al Assad, and his enemies since last summer.
