At least 24 people were reportedly killed and dozens were wounded Monday when two suicide car bombs exploded in different parts of Baghdad, police said. The US military reported a far lower figure for the deadlier of the two attacks. Neither of the attacks took place in the areas of the sprawling city where Iranian President Mahmoud Ahmadinejad was visiting. Also Monday, the US military reported finding a grave with 14 bodies, believed to be members of the Iraqi security forces executed by al-Qaida in Iraq. In Baghdad's deadliest attack, a suicide car bomber reportedly killed at least 22 people and wounded 43 in central Baghdad's Bab al-Mudham neighborhood on the eastern bank of the Tigris, according to police and hospital officials who spoke on condition of anonymity because they were not authorized to talk to the press. Associated Press Television News footage showed a 2-meter crater blown into the street by the explosion, which destroyed numerous cars and trucks and littered the area with shrapnel and debris.
