Two female suicide bombers have blown themselves up at the crowded Monday market in northern Nigeria’s Maiduguri city, causing many casualties, witnesses say.
At least 30 people were killed when the teenage girls detonated themselves.
The second blast occurred while people were trying to help those injured in the first blast.
A third suicide bomber was apprehended before she could detonate her bomb.
Militant Islamist group Boko Haram is waging an insurgency in Nigeria.
It was based in Maiduguri, the capital of Borno state, after its formation in 2002, but it has since been driven out of the city by the military and vigilante groups.
It now controls a large number of towns and villages in Borno, amid fears that it is preparing to launch an assault to capture Maiduguri.
Boko Haram has not commented on the explosions.
