Syrian security forces on Wednesday killed thirteen people across the country, “including two army deserters, two women and a man who died under torture,” activists said.

At least one mortar round struck the outer compound wall of the Turkish embassy in Baghdad on Wednesday, but caused no casualties, an Iraqi official said, amid tensions between the two countries.

Syria's state-owned media on Wednesday accused Qatar of arming and financing opponents of President Bashar Assad's regime.

Beijing on Wednesday defended the Arab League's widely criticized observer mission in Syria, as the U.N. Security Cocil struggled to agree on a resolution on Damascus' crackdown on dissent.
