At least 120 people were killed and 270 others injured on Friday when two suicide bombers blew themselves up and gunmen opened fire during weekly prayers at the mosque of one of Nigeria's top Islamic leaders.

The attack at the Grand Mosque in Kano came just as Friday prayers had started. The blasts came after a bomb attack was foiled against a mosque in the northeastern city of Maiduguri earlier on Friday, five days after two female suicide bombers killed over 45 people in the city.
