Nigerian President Goodluck Jonathan has declared a state of emergency in three states after a spate of deadly attacks by Islamist militant groups.
In a televised address, he said he had given the military powers to take over security in the states of Adamawa, Borno and Yobe.
He also ordered more troops to be sent to the north-eastern states.
Islamist group Boko Haram has been blamed for most of the violence, killing some 2,000 people since 2010.
