Amid increasing Boko Haram attacks, Nigeria’s new president, Muhammadu Buhari, has chose to replace numerous military’s key chiefs.

Since his inauguration in May, Buhari has moved Nigeria’s defence command centre to Maiduguri, the birthplace of Boko Haram, and is setting up the headquarters for a multinational joint taskforce in Chad’s capital, N’Djamena.

It was not immediately clear if the Chief of Defence Staff Alex Badeh and National Security Adviser Sambo Dasuku were also affected by the purge. The Chief of Air Staff, Air Vice Marshal Sadique Abubakar is from Bauchi State, Northeast Nigeria. Atrocities committed by the Nigerian military have hampered USA help because of laws that prevent the United States from providing certain arms to the governments of armed forces accused of gross human rights abuses.

Since 2009, Boko Haram has killed thousands in Nigeria, including pastors and church members.

Meanwhile, Nigerian police say they’re investigating reports that dozens of people were killed in a series of raids by Boko Haram extremists in a remote region of northeastern Borno State.

Buhari’s announcement on Monday was more even-handed. President Buhari has said he will investigate the allegations.

Buhari is also expected to meet US Senate and Congressional Committees on Foreign Relations, as well as the Black Caucus of the US House of Representatives.

“At this stage of our national history especially with the insecurity we presently experience, it is appropriate for us to device new ways and means of confronting this hydra-headed insurgency, without making such initiatives public knowledge”.

The warning was issued after the attack in the capital of N’Djamena killed at least 15 people and injured 80 others, Fox News reported.

Two female bombers blew themselves up near an army camp at Fotokol on Sunday, according to a local security source in the town, the first suicide attack on Cameroonian soil although the area has come under repeated attack by Boko Haram.

Boko Haram has claimed responsibility for the attack, signing a post in Twitter as “Islamic State, West Africa province”.

Mr. Shariatmadari congratulated President Buhari on his election and assured Nigerian of Iran’s support in the fight against terrorism and violent extremism.

Boko Haram’s upsurge in attacks on civilians comes after a four-nation coalition of Nigeria, Niger, Chad and Cameroon pushed out the militants from captured territory earlier this year.
