Boko Haram affected areas

Nigeria's army says it has cleared 10 more camps used by Boko Haram in the north-east of the country. Й The army has recaptured most of the vast area the militants had seized but the Islamists remain active.

Nigerian forces backed by warplanes invaded Islamist group Boko Haram's last known stronghold, the Sambisa forest, on Wednesday, in an effort to finally defeat their six-year-old insurgency, two military sources said.

Nigeria's newly-elected President Muhammadu Buhari said on Wednesday his government would "spare no effort" to defeat Islamist militant group Boko Haram.

ТAt the beginning of the year, Boko Haram controlled some 20 local governmental districts in the three north-eastern states in Nigeria,У Mohamed Ibn Chambas, the Special Representative of the Secretary-General and Head of the UN Office for West Africa (UNOWA), said. ТToday, Boko Haram holds only a few areas in Borno State.Т

Nigeria ramped up security nationwide on Wednesday before general elections this weekend, shutting land as well as sea borders and vowing to crack down hard on political unrest.

Central and West African states will hold a summit next month to agree a common strategy to combat the Boko Haram insurgency, their leaders said on Wednesday.

The Nigerian army said Tuesday that it had repelled Boko Haram from all but three local government districts in the northeast, claiming victory for its offensive against the Islamist insurgents.

Nigeria has brought in hundreds of mercenaries from South Africa and the former Soviet Union to give its offensive against Boko Haram a shot in the arm before a March 28 election, according to regional security, defence and diplomatic sources.

If approved, the new force would receive U.N. funding and would be likely to result in a bigger and better resourced operation than the offensive currently being mounted against the militants by Nigeria and its neighbours.
