Barely a few hours after the killing of 40 students at the College of Agriculture, Gujba, Yobe State, the Defence Headquarters yesterday placed the military and other security agencies on red alert.

Besides, there were indications that military commanders and other security chiefs may henceforth be made to account for security breaches by Boko Haram in their areas of operations.

Following renewed strikes by Boko Haram in Borno-Yobe axis, a former Governor of Borno State, Ali Modu Sheriff, has shelved plans to speak on the causes of the insurgency in the Northeast.

It was gathered that security chiefs, led by the Chief of Defence Staff Admiral Sa’ad Ibrahim, held a situation appraisal session in conjunction with the National Security Adviser, Mr. Sambo Dasuki.

A top source said: “One of the decisions taken is to put in place heavy security build up in every nook and cranny in the state, especially schools that have become the targets of the insurgents.

“The situation in Borno and Yobe requires drastic measures. This is why the military and security agencies have been placed on red alert by the Defence Headquarters. It is obvious that Boko Haram is changing tactics.

“All commanders and security chiefs in flashpoints may henceforth account for security breaches by the insurgents. This is part of plans to keep troops on their toes.

“Inter-agency cooperation is another challenge being addressed by the security chiefs. In the last one week, all the agencies have been undergoing security session on why inter-agency collaboration is required at this critical stage of the fight against insurgency.”

Responding to a question, the source added: “President Goodluck Jonathan has been briefed on the massacre of students at the College of Agriculture in Gujba.

“As the Commander-In-Chief of the Armed Forces, the President is expected to announce far-reaching actions against the insurgents.”

Sheriff has explained why he shelved plans to speak on the insurgency in the Northeast.

Sheriff, who had wanted to clarify the allegations against him on the insurgency in Borno State, said he could also not meet with former members of the defunct All Nigeria Peoples Party (ANPP) because of killings in Borno.
