Suspected Boko Haram suicide bombers killed at least 27 people and wounded 83 in northeast Nigeria on Tuesday, local sources said.

A woman bomber blew herself up and killed 27 others at a market in the village of Konduga near Maiduguri, the epicentre of the conflict between government forces and Boko Haram terrorists, according to a village head and an official from a regional militia.

Two suicide bombers also blew themselves up at the gates to a nearby refugee camp, with no others killed but many injured, said an emergency service official.
