Authorities in northeastern Nigeria say 12 people are dead after suicide bombing attacks not far from the city of Maiduguri.
Police spokesman Victor Isuku said Monday that the attacks were carried about by five female bombers in Kofa, about 8 kilometers (5 miles) from Maiduguri.
The first attack killed several people near a mosque, while five others were killed in a house.
Last late year Nigeria declared that the Boko Haram extremist group had been crushed but attacks continue, often with young women strapped with explosives to carry out suicide attacks.
Many of the young women are believed to be among those abducted by the jihadists, who have pledged their allegiance to the Islamic State.
