While much of the world's attention focuses on a possible war with North Korea, the war currently being fought in Syria grinds on. March of 2013 was a month of grim milestones in Syria. It marked two years since the start of hostilities; the number of war refugees passed one million; and it was was the bloodiest month to date, with more than 6,000 people killed. Neither the pro-Assad forces, nor the group of rebels opposing them have gained much ground recently, and little or no progress has been made by international agencies to halt the bloodshed. The following photographs come from across Syria, taken over the past six weeks, showing just some of the devastation in Aleppo, Deir al-Zor, Homs, Deraa, Idlib, and Damascus.
