Dozens have been killed in a gun and bomb attack during Friday prayers at one of the biggest mosques in the Nigerian city of Kano, reports say.

Many more people have been hurt, with one rescue official putting casualty figures at just under 200.

The Central Mosque is where the influential Muslim leader, the Emir of Kano, usually leads prayers.

The emir recently called for people to arm themselves against Islamist militant group Boko Haram.

The group has been waging an insurgency in Nigeria since 2009 and has killed more than 2,000 people this year, rights groups say.
