The Nigerian military says its soldiers killed 14 suspected Islamist militants Sunday during an early morning raid on a house in the main northern city of Kano.
Military officials said one soldier died and another one was seriously wounded in the raid. The military's casualty figures have not been independently confirmed.
Those targeted were allegedly members of the Islamist extremist group Boko Haram, a group often blamed for launching attacks on Christian holidays.
Boko Haram began violent operations in 2009. It has killed an estimated 3,000 people in attacks on churches, schools, government and newspaper offices, as well as in attacks on security forces, markets and the country's communications infrastructure.
However, human rights groups have accused Nigeria's security forces of killing hundreds more in operations to subdue the militant group. Most of the violence has been in northern Nigeria.
