A rocket was fired into the international Green Zone in Baghdad on Saturday and a witness said it appeared to have landed in the U.S. embassy grounds, according to Reuters. U.S. embassy spokesman Lou Fintor said a rocket landed in a sparsely populated area of the Green Zone and that two people were slightly wounded. He said he could not confirm that it landed within the U.S. embassy compound. "The embassy is functioning normally," he said, adding that the two injured were not embassy staff. Loudspeaker warnings urged people to take cover. "This is not a drill," the warning said. Several people in the Green Zone said they had heard what may have been a mortar or rocket go past, but could not say where it landed. A double rocket attack on the Green Zone wounded six people earlier this week. The area, which stretches over several square kilometres (miles) houses Iraqi government offices, embassies and other foreign facilities.
