BAMAKO: Mali’s army has arrested Alaye Bocari, a leading financial backer of a militant group responsible for an expansion of deadly attacks in the West African nation, military and defense sources said on Monday.

The attacks carried out by the Massina Liberation Front (MLF), led by radical preacher Amadou Koufa, have helped shift Mali’s three-year-old conflict from the remote desert north ever closer to its populous south.

Bocari is among Koufa’s close collaborators according to intelligence gathered by the military, said army spokesman Col. Souleymane Maiga.

“He was arrested on Nov. 13 in the region of Mopti by an army patrol acting on information given by the population,” he said.

The arrest, one of around 30 carried out so far during an army operation launched late last month, was confirmed by a defense ministry spokesman who declined to give further details.

France launched a military intervention in its former colony in 2013 to drive back militants who seized the north a year earlier creating what Paris feared could become a base for attacks on Europe. The operation drove the fighters from major population centers.

Attacks mainly targeting Malian soldiers and UN peacekeepers persist however, and the military action made French interests the declared targets of groups including Al-Qaeda’s regional franchise.
