Twenty-four of the 80 people taken hostage by Boko Haram in the north of Cameroon yesterday were released as Cameroonian armed forces pursued the Islamist extremists, according to a government source.
The Boko Haram fighters then fled back into Nigeria, with the fate of the rest of the hostages taken in the raid, the worst of its kind to date, still unknown.
An army officer based in Cameroon's far north said Boko Haram had attacked two villages and kidnapped what Cameroonian state media said were 80 hostages.
As the militants retreated, the Chadian army said it was putting 400 military vehicles, attack helicopters, and still unspecified number of soldiers amassed in northern Cameroon into action against Boko Haram, as part of what has become a regional effort to defeat the notoriously violent group.
