Presidential media aide, Reuben Abati has announced the sack of Gen. Andrew Owoye Azazi as the National Security Adviser. Col. Sambo Dasuki has been named as his replacement. Also dropped is the minister of defence, Alh. Bello Halliru
Abati, however, did not give reasons for the President's decision.
On his arrival from the UN Earth Summit in Rio de Janeiro, Brazil, earlier on Friday, the President summoned an emergency meeting of all his security Chiefs.
The meeting, which lasted about one-and-a-half hours at the Presidential Villa in Abuja, was attended by Azazi and Bello.
Azazi had told State House Correspondents that the meeting reviewed the security situation in the country, saying, "the security situation is under control".
The Minister of Police Affairs, retired Navy Capt Caleb Olubolade, after the meeting also said that the security Chiefs "comprehensively" briefed the President on the security situation.
"It was a useful discussion; certain areas where we have problems, we have to tackle them. We want to see how the security agencies will be more effective and the role the citizens have to play.
"We have been there for about one-and-a-half hour; it was very useful," Olubolade had said.
Others at the meeting were: the Chief of Defence Staff, Air Chief Marshall Oluseyi Petinrin, Chief of Army Staff, Gen Azubuie Ihejiria, the Chief of Naval Staff, Vice Admira Ola Ibrahim, and the Chief of Air Staff, Air Marshall Dikko Umar.
Acting Inspector General of Police Mohammed Abubakar and the Director-General of the SSS, Mr. Ita Epeyong, were also at the meeting.
