At least four people were killed in twin suicide attacks in the far north of Cameroon in two districts of Waza, an area that has been repeatedly targeted by Boko Haram terrorists from neighboring Nigeria, security sources and state media said Wednesday.

"Two suicide bombers blew themselves up on the Nigerian border on Tuesday night, a security source who did not wish to be named, said.

State radio confirmed the report, saying two assailants detonated explosives, "killing six people, including themselves".

The attacks are the first of their kind in Waza, a town on the edge of a national park teeming with lions, elephants and other wildlife that used to draw tourists but which has been abandoned by foreign visitors since the region, which borders Nigeria and Chad, became a target for extremist attacks.

The attacks have been blamed on Boko Haram, a terrorist group seeking to create a hardline entity in northeast Nigeria.

Over the past year Boko Haram has stepped up cross-border attacks in Niger, Chad and Cameroon while also continuing to mount shooting and suicide assaults on markets, mosques and other mostly civilian targets within Nigeria itself.

Cameroon is part of a regional coalition helping Nigeria combat the terrorists.
