PARIS (AP) — Nigeria’s president Goodluck Jonathan says Boko Haram, which is holding more than 200 girls captive, is “acting clearly as an al-Qaida operation” and is no longer a local problem.

President Jonathan joined four other African leaders and representatives of France, Britain and the US on Saturday to hammer out details of an international response to the Islamic extremist group.

French President Francois Hollande said the effort will involve sharing intelligence, protecting borders, and quick action in a crisis.

Hollande also emphasized that Boko Haram had clearly established ties with other terror groups in Africa, making it a problem throughout the continent and beyond.

Hours after yet another attack in a Boko Haram stronghold, African leaders and Western officials drew the outlines of an international plan to share intelligence and coordinate the fight against the Islamic extremist group holding more than 200 girls captive.

The militants, who claim to be fighting a holy war in Nigeria, move freely across the border into neighbouring Cameroon, where a Chinese engineering firm’s camp came under attack late Friday. The camp was in the same nearly trackless parkland where the school girls were spirited away.

The leaders of Nigeria, Niger, Cameroon, Chad and Benin met Saturday with French, US and British officials in hopes of coordinating strategy and sharing intelligence to find the girls.

Boko Haram has offered to exchange the 276 girls who remain captive for jailed insurgents, and threaten otherwise to sell them into slavery.

“Boko Haram’s strategy, contrary to all civilization, is to destabilize Nigeria and to destroy the fundamental principles of human dignity,” Hollande said during the working lunch. “More than 200 young girls threatened with slavery is the proof.”

Officials have said there will be no Western military operation. British officials say Nigerian President Jonathan, who has reluctantly accepted outside help, has ruled out swapping prisoners for the girls.

On Friday, Jonathan cancelled a trip to the town where the girls were seized, apparently due to security concerns.

Signs are growing that some Nigerian troops are near mutiny, complaining they are overwhelmed and outgunned by Boko Haram. Soldiers have told The Associated Press that some in the ranks actually fight alongside the group. Last year, Jonathan said he suspected that Boko Haram members and sympathizers had infiltrated every level of his government and military, including the Cabinet.

That complicates attempts to share intelligence. The US, France and Britain have all sent experts to help find the girls, but French and American officials have expressed concerns about how any information might be used.

The northeastern region where the girls were kidnapped has suffered five years of increasingly deadly assaults by Boko Haram. Thousands have been killed, including more than 1,500 civilians this year.

Cameroon, which borders the region, has begun to take the threat more seriously after years of dismissing it as a Nigerian problem, French officials say.

France has negotiated the release of citizens held by Boko Haram in Cameroon and officials were hoping Saturday’s summit would set the outlines of a more international approach.

Chinese state media reported that 10 people were missing in the Friday night attack on the camp in a region where Boko Haram has previously abducted foreigners, including a French family of seven and a priest.

Hollande’s administration successfully negotiated the release of the French citizens, and officials in Paris said France’s experience dealing with Boko Haram as well as its good relations with the governments concerned were the impetus for the summit.

China is a major investor in Cameroon, helping build infrastructure, public health projects and sports facilities and importing crude oil, timber and cotton.
