"Over 146,000 people, more than a third of them civilians, have been killed in Syria's uprising-turned-civil war which enters its fourth year this month, the Syrian Observatory for Human Rights said on Thursday.
The last U.N. figures, released in July 2013, put the death toll at least 100,000 but the United Nations said in January it would stop updating the toll as conditions on the ground made it impossible to make accurate estimates."
