JOHANNESBURG - Nigerian president Goodluck Jonathan has vowed "to leave no stone unturned" in tracking down the perpetrators of a mosque attack that killed 120 people in that country.

Jonathan urged the nation "to confront the common enemy" after the gun and bomb attack during yesterday's prayers in the northern city of Kano.

Hundreds of people were injured in the attack which officials say bears the hallmarks of the Boko Haram militant group.

Police say the bombers blew themselves up in quick succession and then gunmen opened fire on those who were trying to escape.

On Friday it was reported that 81 people had been killed in the attack.

Blasts from the coordinated assault rang out as scores of people packed into the ancient building's courtyard for afternoon prayers. "These people have bombed the mosque. I am face to face with people screaming," said local reporter Chijjani Usman.

The mosque is next to the palace of the emir of Kano, the second highest Islamic authority in Africa's most populous country and a vocal critic of Boko Haram. The emir, former central bank governor Lamido Sanusi, was not present.

Boko Haram, a Sunni jihadist movement which is fighting to revive a medieval Islamic caliphate in northern Nigeria, regards the traditional Islamic religious authorities in Nigeria with disdain.

It has attacked mosques that do not follow its radical ideology in a bloody near six-year campaign that has also targeted churches, schools, police stations, military bases and government buildings.

The group has been waging an insurgency in Nigeria since 2009 and has killed thousands of people this year.

The death toll is expected to rise as emergency officials are still combing the scene.
