Police officials say the deadlier attack took place today evening when a bomb exploded in a commercial street in the Abu Ghraib area just outside the capital, killing three people and wounding five others.
One hour later, two policemen were killed when gunmen sprayed with bullets a security checkpoint in the former al-Qaeda strong-hold city of Fallujah, 65 kilometres from Baghdad.
Two medical officials confirmed the casualty figures. Both officials spoke on condition of anonymity because they were not authorised to talk to media.
