Blasts shake Baghdad

More than a dozen blasts have shaken central Baghdad and thick plumes of smoke were seen rising above the Green Zone housing Iraq’s interim government.

The blasts were reportedly caused by mortars

Witnesses said mortars appeared to have been fired early on Sunday morning into the Green Zone from the city’s Sadr City district – a stronghold of supporters of Shia leader Muqtada al-Sadr.
  
Sirens echoed across the zone. The US military had no immediate word on any damage or casualties. 
  
The Green Zone has been a regular target of attack, often by mortar or car bomb, in recent months. Mortar bombs were fired at the first sessions of the interim assembly last week.
