Syrian army defectors stand guard on a rooftop to secure an anti-Syrian regime protest in the Deir Baghlaba area in Homs province, central Syria, on Friday, Jan. 27, 2012. Armed forces loyal to President Bashar Assad barraged residential buildings with mortars and machine-gun fire, killing at least 30 people, including a family of women and children during a day of sectarian killings and kidnappings in the besieged Syrian city of Homs, activists said Friday.
