Lagos - Nigeria's president-elect Muhammadu Buhari needs a comprehensive, not just military, plan to defeat Boko Haram, experts said on Thursday, after the former army general vowed to crush the Islamists.
"Military force alone is not enough to annihilate the movement," Nigeria researcher Marc-Antoine Perouse de Montclos, from the Chatham House international affairs institute in London, told AFP.
Boko Haram may be "backed into a corner" but "is not clinically dead", he added.
The group's attacks and suicide bombings in northeast Nigeria have claimed more than 13,000 lives since 2009, with the insurgency -- and the government's handling of it -- a key election issue.
Boko Haram has moved beyond northeast Nigeria, attacking Cameroon and Niger, which were for long considered operating bases, giving the impression of an unstoppable force.
But the involvement of both countries, and notably Chad, in Nigerian border areas south of Lake Chad, alongside Nigerian troops operating further inside the northeast, seems to have stopped their advance.
- 'Win peace' -
Nigeria has taken back the strategic town of Baga, Chadian troops Gamboru and Dikwa near Cameroon, while Chadian and Nigerien forces have recaptured Malam Fatori and Fotokol on the Niger border.
The most symbolic loss for Boko Haram came last Friday, on the eve of elections the heavily armed militants vowed to disrupt.
Nigeria's army, on the offensive after being regularly outgunned and outmanoeuvred, seized the group's headquarters in Gwoza, from where leader Abubakar Shekau proclaimed a caliphate last year.
Former military ruler Buhari on Wednesday declared war on Boko Haram, vowing they "will soon know the strength of our collective will and committment to rid this nation of terror and bring back peace".
He then told the BBC in an interview: "With the co-operation of our neighbours, Cameroon, Chad, Niger and the international community, and the commitment we are going to get from the military, I think it will take us a much shorter time to deal with them," he told the BBC in an interview.
His campaign spokesman Shehu Garba told AFP on Thursday there would be a "more effective military response than seen under the last administration", including development programmes and "soft power".
Buhari headed a military government in the 1980s and is a former governor of the old Northeastern State, which includes modern-day Borno, Yobe and Adamawa states hit by fighting.
The 72-year-old, a northern Muslim, has criticised Boko Haram's radical brand of Islam and last year escaped with his life after an attack blamed by some on the militants.
Montclos said Boko Haram has "more to fear from Muhammadu Buhari, who knows the terrain and will be perceived as legitimate by northern Muslims" than his beaten opponent, President Goodluck Jonathan.
Jonathan, a Christian from the south, was widely perceived in the north to have been indifferent to the insurgency and its devastating effects.
"In many respects, Buhari walks into a situation where a military victory has been achieved. Now he needs to consolidate the peace," said J. Peter Pham, from the Atlantic Council.
Montclos also said Buhari should strive to "win peace" rather than "win the battle" against the insurgents, even if they have been weakened.
But the insurgency is far from over. Hours after the recapture of Gwoza was announced, 23 people were found decapitated in a northeastern village.
There were attacks in northeastern Gombe state and neighbouring Bauchi last weekend, while on Thursday, 10 people were killed in an explosion in Gombe city.
