At least five people were killed Monday when two female suicide bombers blew themselves up at a market in northeast Nigeria and Boko Haram launched a major assault on police in two state capitals.

The blasts in Maiduguri and dawn raid in Damaturu came just days after a deadly mosque attack in the northern city of Kano left at least 120 people dead and hundreds more injured.

Almost daily attacks have heightened tensions in Nigeria's far northeast and sparked fears of unrest beyond the country's borders.
