At least six people have been killed in a bomb explosion at a funeral ceremony in the western Iraqi province of al-Anbar, police say.

Fifteen other mourners were also wounded after the bomber set off a belt full of explosives at a funeral in the town of Haditha, 260 kilometers (160 miles) west of the capital Baghdad, on Monday.

"At the moment people were carrying the coffin, a suicide bomber exploded himself in the middle of the crowd, killing five," Haditha's mayor, Abdel Hakim Mohammed, said adding that the funeral was for a member of the al-Daghaytha tribe, which included members of the police and army, AP reported.

The attack came shortly after a roadside bomb explosion targeted an army patrol in Fallujah killing one civilian and injuring five other.
