In a barrage of mortar shells, Syrian forces killed 200 people and wounded hundreds in Homs in an offensive that appears to be the bloodiest episode in the nearly 11-month-old uprising.
Activists say the assault in Homs, which has been one of the main flashpoints of opposition during the uprising, comes as the U.N. Security Council prepares to vote on a draft resolution backing an Arab call for President Bashar Assad to give up power.
The government denied the assault. Syrian TV said the reports were untrue and come in the context of "incitement by the armed
groups" against Syria to be exploited at the Security Council.
