Officials say a bomb left on a Baghdad minibus and a suicide truck bomb north of the Iraqi capital have killed seven people. The two separate attacks on Tuesday followed a particularly bloody day that left more than 70 people dead, according to a report of the Associated Press. A police officer said the minibus bomb killed five commuters and wounded 25 in Sadr City. Another police officer said a suicide bomber set off his explosives-laden truck after passing a police checkpoint in the town of Tarmiyah to the north of Baghdad, killing a policeman and a civilian. Nine were wounded. Two medical officials confirmed the casualties.
