The death rate in Syria's civil war is accelerating, with more than 6,000 deaths making March the deadliest month of the conflict that began more than two years ago. The deaths include hundreds of women and children as well as a large number of rebel fighters and government troops, according to the Syrian Observatory for Human Rights activist group, which estimates around 120,000 people have been killed since the conflict began, the BBC reports. More people died in the first few months of this year than in the entire first year of the conflict, and the number of refugees has now topped 1 million. (More Syrian uprising stories.)
