Syrian forces have launched new operations targeting opposition activists as the bombardment of the city of Homs continues for a 12th day. Syrian tanks have reportedly shelled areas of Hama, Syria’s fourth largest city. Raids against opposition activists have also been conducted in the capital Damascus. In Homs, an oil pipeline was attacked earlier today, setting off a major blaze. The government of Syrian President Bashar al-Assad, meanwhile, has announced it will hold a referendum on a new draft constitution later this month, followed by parliamentary elections within 90 days. Opposition activists are already vowing to boycott the votes, calling them a front to maintain Assad’s grip on power.
