A female suicide bomber blew herself up in a cafe in Cameroon's far north region Sunday, killing at least one person and wounding 28 others, witnesses told AFP. Witnesses said the woman entered the cafe at around 7:00 am (0600 GMT) before detonating her explosive vest in Bia, a village close to the border with Nigeria. The area has seen frequent attacks by the Boko Haram jihadist group in recent years. Those hurt in the blast were taken to a nearby hospital, witnesses said.
