Syrians in Damascus are cleaning up after two mortar blasts killed at least one and injured several. The mortars blew out the windows of nearby shops in the city's central Shaalan district -- leaving charred wreckage scattered. The source of the attack is unknown. The deadly blasts come a day after the Organization for the Prohibition of Chemical Weapons won the 2013 Nobel Peace Prize. The OPCW is overseeing the destruction of chemical weapons in Syria.
