Three explosions occurred outside the heavily guarded Green Zone on Sunday, killing seven Iraqi civilians and wounding eight, a US official said. The official said the blasts, caused by mortars or rockets, occurred near Iraq's Defense Ministry, which is located just inside the Green Zone on the west side of the Tigris River. One of the explosions occurred in a parking lot. The official spoke on condition of anonymity since the blasts occurred outside the Green Zone, where Iraq's parliament meets and the US and British embassies are located. Lt. Col. Falah al-Mohammedawi of Iraq's Interior Ministry gave a lower casualty count, saying six Iraqis were killed and three wounded.
