Nigeria's President Muhammadu Buhari has hailed security agencies for the arrest of Igbo separatist leader Nnamdi Kanu and the raid on Yoruba activist Sunday Adeyemo's home.

It's the first time the president has spoken about the arrest and extradition of Mr Kanu, the leader of the Indigenous People of Biafra (Ipob) movement.

He also commended the controversial raid on the residence of the prominent Yoruba activist whom he described as "conducting acts of terror and disturbing the peace under the guise of protecting fellow kinsmen".

He praised the security agencies for demonstrating "significant deftness, guile and secrecy in carrying out these missions".

The president remained silent on how Mr Kanu, who also has British nationality, was arrested.

It came as a member of the UK's parliament has asked about the circumstances surrounding the repatriation of Mr Kanu to Nigeria, according to a notice on the parliament's website.
