The Boko haram terrorists leader, Abubakar Shekau, and a splinter group, Ansaru were on Wednesday sanctioned by the United Nations Security Council.

According to Reuters, Shekau is the first individual while Ansaru is the first entity to be so sanctioned since the Islamist militant group was blacklisted.

Following the sanction, Boko haram leader, Shekau and Ansaru will be banned from international travel while their assets would be frozen under the UN al Qaeda sanctions list.

Russia had placed a “technical hold” on the designations two weeks ago because it needed more time to review the listings, but diplomats said they lifted the hold on Wednesday, allowing the sanctions to come into force.

It would be recalled that last month, the Security Council al Qaeda Sanctions Committee blacklisted Boko Haram at the request of Nigeria, following the kidnap of over 200 girls from the Government Secondary School, Chibok, Borno State, on April 14 by the sects.

Ansaru broke off from the Boko Haram sect in protest after it killed 186 mostly Muslim civilians in Kano in 2012.

Following Shekau’s many attrocities and in a bid to arrest him, the US Secretary of State, John Kerry, authorised a reward of up to $7m for information leading to his location a year ago.
