YAOUNDE, Cameroon — At least 15 people were killed as two female suicide bombers carried out the latest attack in Cameroon’s far north, the government said Thursday, and another 42 people were wounded.
The attackers entered the town of Waza late Wednesday and one detonated explosives near a group of youths, Governor Midjiyawa Bakary said.
Nigeria-based Boko Haram extremists have been crossing borders to stage attacks in countries, including Cameroon, that contribute to a military force that seeks to eliminate the insurgency. The Islamic extremists have killed more than 20,000 people in their eight-year existence and abducted thousands of others.
Boko Haram increasingly has used girls and young women to carry out attacks on marketplaces, checkpoints and other targets. Some young women who escaped the extremist group have said girls are drugged and forced to carry out suicide missions.
The attacks in Cameroon’s far north, the poorest part of the country, have been a factor in returning 13,000 Nigerian refugees who had fled Boko Haram back to their nation.
The suicide attacks, roadside bombings, and raids on villages also have been ‘‘complicating humanitarian operations and subjecting civilians to persistent danger,’’ the UN humanitarian agency said.
The Boko Haram-fueled crisis is part of what the UN has called the largest humanitarian crisis in 70 years, with millions facing hunger.
