Who are Nigeria's Boko Haram terrorists?

Boko Haram (recently renamed Iswap) fights against Western influence in Nigeria and aims to impose its version of Sharia law in the country.

The group declared an Islamic caliphate in Gwoza, along the Cameroon border, in August 2014.

Boko Haram has raided several cities in the north of the country in a bid to take control of more land.

Three states − Adamawa, Borno and Yobe − have been under a state of emergency since May 2013, due to Boko Haram's attacks.

The group has killed more than 3,000 people since the beginning of 2015.

The Multinational Joint Task Force – with its headquarters in the Chadian capital N'Djamena, – comprises some 8,700 troops from Nigeria, Niger, Chad, Cameroon and Benin. It is expected to be more efficient than the ongoing regional offensive, which scored some success in recent months, the Nigerian military said.

The announcement came as Buhari is in Cameroon to hold discussions with President Paul Biya to improve the regional offensive and improve relations between the two countries, which deteriorated over land disputes in 1980s.

Cameroon also announced it would send 2,000 military reinforcements to the north of the country, on the border with Nigeria, following deadly attacks blamed on Boko Haram that have left hundreds dead in recent weeks.
