Boko Haram affected areas

The leaders of Nigeria and Cameroon pledged on Thursday to improve the exchange of intelligence and security cooperation along their border in a bid to tackle Nigerian Islamist militant group Boko Haram.

Cameroon will deploy an extra 2,000 troops along its northern border with Nigeria to fight militant Islamist group Boko Haram, state television reports.

While acknowledging progress made against Boko Haram following joint regional military efforts in recent months, the United Nations Security Council today encouraged increased regional cooperation to stamp out the terrorist group, which the Council strongly condemned for its ongoing deadly violence, human rights abuses and mass abductions in the Lake Chad Basin.

The conflict between Boko Haram and the Nigerian government is displacing thousands on both sides of the country's border with Cameroon to the northeast and Niger to the north, the UN refugee agency (UNHCR) said on Tuesday.

Suspected Boko Haram militants have killed at least 45 people in northeastern Nigeria, the latest in a series of deadly attacks in the area. Й The attacks came just hours after President Muhammadu Buhari replaced all of Nigeria's military chiefs in another step aimed at halting the six-year Boko Haram insurgency.

Boko Haram fighters have waged new attacks on a series of towns and villages, killing at least 160 people. Й Reacting to the series of attacks in the northeastern states, President Muhammadu Buhari said the violence highlighted the need "to form a more effective international coalition against insurgency and terrorism in Nigeria and neighbouring countries".

An attack by suspected Islamist Boko Haram fighters in Niger has killed at least 38 people, officials say. Й Boko Haram is based in Nigeria but is being challenged by a multinational force, including soldiers from Niger.

Suicide bombers in ChadХs capital attacked security hubs Monday, killing at least 23 people in strikes that raised fears of a widening reach by the Islamist faction Boko Haram, reports said.

New Nigerian President Muhammadu Buhari met his regional counterparts in Abuja on Thursday to set up a joint military force against Boko Haram, the latest sign of his intent to crush the Islamist militant group early in his tenure.

Five African countries have agreed to set up a joint military force led by Nigeria to fight the Islamist militant group Boko Haram. Й Most of the troops will be from Nigeria with Chad, Cameroon, Niger and Benin also contributing.
