This week, fierce fighting between troops and rebels reached the Syrian capital, the central bastion of Bashar Assad's rule, shattering parts of the city and sending thousands of people fleeing to neighboring Lebanon and Iraq. Activists and residents reported a tense calm in Damascus Saturday but said sporadic gunfire and explosions could be heard throughout the night. (AP Photo)
