"There is no doubt that Boko Haram is responsible and will be brought to justice for this new humanitarian horror," Hollande said at a press conference yesterday in Algiers after meeting his Algerian counterpart Abdelaziz Bouteflika during a visit that focused on the threat posed by jihadists in the region.
"We have underscored our concern and our solidarity" following "this barbaric attack", Hollande added.
The Chadian government also blamed Boko Haram for the suicide bombings that targeted two police buildings in N'Djamena.
