Inside Kano mosque after gun and bomb attack

In Nigeria, the number of people who died in a gun and bomb attack on a mosque in the Northern city of Kano has risen to more than 100.

Boko Haram, the Sunni Islamist militant group, is being blamed for the attack. Human rights groups in Nigeria say the group has killed more than 2,000 people this year.
