Nigeria has been hit by a fresh wave of violence targeting the country’s Christian communities.
Reports from the capital Abuja say 17 people were killed in Mubi in Adamawa state as gunmen opened fire in a town hall where members of the Christian Igbo group were meeting.
There were also reports of a deadly attack in Adamawa’s capital, Yola.
The Islamist Boko Haram group said it had carried out the attack in Mubi and another in Gombe in which six people died.
The group has staged numerous attacks in northern and central areas in recent months.
On Christmas Day, Book Haram attacked a church near the capital, killing dozens of people.
Meanwhile, President Goodluck Jonathan has declared a state of emergency in Yobe and Borno States, as well as Plateau State in Central Nigeria and Niger State in the west, following a surge in ethnic and sectarian violence.
