Authorities in northern Cameroon say at least 15 people have died and dozens are wounded after two suicide bombing attacks.

Midjiyawa Bakary, governor of Cameroon's far northern region, told The Associated Press that the attacks took place late Wednesday near the country's border with Nigeria.

He said at least 50 people who were wounded in the attacks on a video club and a mosque were taken to regional hospitals.

Northern Cameroon has suffered scores of attacks blamed on militants from the Islamic extremist group Boko Haram.

Boko Haram was founded in Nigeria and has pledged its allegiance to the Islamic State group.

Boko Haram has stepped up its attacks in Cameroon and other neighboring countries that have been helping Nigeria's military to try to defeat the extremists.
