Iraqi officials say a twin suicide bombing hit a police station in Baghdad's westernmost suburb, killing at least five policemen.

Thursday's attack comes a day after the deadliest violence in Baghdad this year killed 93 people across the Iraqi capital and wounded 165 in a wave of bombings that was claimed by the Islamic State group.

A police officer says the two suicide bombers hit the station in the western suburb of Abu Ghraib at dawn.

He says the first bomber blew himself up at the station's gate, followed by the second who detonated his explosives inside the building.

The explosion also left 12 policemen wounded.

A medical official confirmed causality figures.

Both officials spoke on condition of anonymity as he was not authorised to release information.
