Jihadist militants on motorcycle killed six French tourists and two Nigeriens (a guide and a driver) in a wildlife park east of Niger’s capital on Sunday, according to the officials.

The group was attacked in a giraffe reserve near Koure region about 70km southeast of Niamey in the Tillaberi region, where ISIS-linked militants are active.
