Insurgents in Iraq fired a barrage of mortar rounds into central Baghdad Thursday, killing at least one person and wounding several others.
Police say some of the mortars landed in the Green Zone -- the heavily fortified enclave that houses Iraqi government offices and several foreign embassies.
Last week, a mortar attack on the Green Zone killed four employees of a British security company.
Meanwhile, the U.S. military is planning to temporarily increase the number of American troops in Iraq to bolster security ahead of Iraq's January election.
The Defense Department said Wednesday the size of U.S. forces in Iraq will increase to 150,000 from its current level of 138,000.
Iraq's interim government has rejected calls from some Sunni parties to postpone the vote because of security concerns.
