Terrorism is “resilient” but the Islamist militant group Boko Haram has been defeated militarily, Nigeria’s army chief Lt Gen Tukur Yusuf Buratai has told BBC Hardtalk.

Speaking last Thursday he told Stephen Sackur his army had succeeded in pushing back Boko Haram although they had not been completely eliminated.

When Muhammadu Buhari became president of Nigeria in 2015, he vowed to eradicate Boko Haram and bring security and stability to his country.
