Two explosions struck the Green Zone in Baghdad on Monday, slightly wounding three people, according to the US Embassy. The first attack was about 2 p.m. when a rocket fell in the heavily fortified area in central Baghdad, causing the injuries, embassy spokesman Lou Fintor said. He did not provide more details about the nationalities of those injured or the exact location of the strikes, citing security concerns. Another explosion occurred at about 4:20 p.m. and preliminary reports indicated it was a rocket as well, Fintor said. That attack caused no injuries or deaths and only minor damage, he said. The Green Zone, which houses the US and British embassies as well as thousands of American troops, has been frequently targeted by mortars and rockets but the attacks rarely cause serious casualties.
