Assailants on Tuesday targeted convoys of the interim government's ministers of environment and education in two separate bombings in Baghdad, officials said. Neither of the ministers was hurt, but at least five people were reported dead. In one of the attacks, a car bomb exploded in the southern Baghdad neighborhood of Kadisea as Environment Minister Miskhat Moumin was passing through in a convoy, ministry spokesman Dalal Ali said. Moumin escaped unharmed, Ali said. "However, four people were killed in that blast," said a police brigadier speaking on condition of anonymity. Ziyad al-Hashimi of Baghdad's Yarmouk hospital said at least two other people were injured. In a second attack around the same time in the western Baghdad district of al-Khadra, a roadside bomb exploded as a convoy of vehicles was headed to pick up Education Minister Sami Mudhafar, the police said. The education minister was not in the convoy at the time of the attack and was not wounded, the police brigadier said. The blast killed one of Mudhafar's bodyguards and wounded two others, he said.
