Nigeria's President Goodluck Jonathan sacks military chiefs
Nigeria's President Goodluck Jonathan has sacked his military high command, his spokesman Reuben Abati has said, according to the BBC.
No reason was given but the dismissals come amid growing concern about the military's failure to end the Islamist-led insurgency in northern Nigeria.
Mr Abati said Air Marshal Alex Badeh replaces Admiral Ola Ibrahim as the new chief of defence staff, the most senior post in the military.
Boko Haram has been waging a four-year insurgency in Nigeria.
Mr Jonathan imposed a state of emergency in three northern states in May 2013, giving the military wide-ranging powers to end the insurgency.
However, Boko Haram has continued with its campaign of violence - including attacks on two military barracks and an air base last month.
On Tuesday, the group carried out a car bomb attack in the north-eastern city of Maiduguri, killing at least 17 people.
United Nations figures suggest more than 1,200 people have been killed in Islamist-related violence since the state of emergency started.
Mr Abati said the new appointments would come into effect immediately.
