The Nigerian Army has issued a red alert across the country after "very credible" intelligence reports warned of imminent Boko Haram attacks on the Federal Capital Territory (FCT), which includes Nigerian capital Abuja. The warning comes amid rising tensions within the Islamist terror group over leadership disputes.

While Islamic State (Isis) recently announced former spokesperson of the Nigerian terror group Abu Musab al-Barnawi as Boko Haram's new leader, its former chief Abubakar Shekau has disputed the appointment and said he is still the leader of the militant group.

Meanwhile, intelligence reports received by the Nigerian army said that Boko Haram terrorists have completed arrangements to launch attacks at crowded places like school, markets and other sensitive areas in the capital territory. They also plan to target police and military establishments.

A communication sent to all military posts in the country from the Chief of Army Staff, Lt General Tukur Buratai's office, stated: "Information at the disposal of this headquarters strongly point to plans by Boko Haram terrorists group to attack various locations in the country. The targeted areas include but not limited to police stations, prison facilities, schools and market places."

Suleiman signed the message on behalf of the army chief, which also warned that the intelligence information indicates Boko Haram terrorists "intend to target police stations and formations in Abuja, Kano and Imo states".

"Similarly, schools that are being re-opened in Adamawa, Borno and Yobe states are also at risks, in the light of the wide ranging plot by the group to cause large-scale destruction.
