YAOUNDE, Cameroon -- A multinational force freed 900 hostages held by Nigeria's Boko Haram extremists, killed more than 100 fighters and arrested 100 others last week, Cameroon's government spokesman said Wednesday.
Hostages from Cameroon, Nigeria and Chad were held in several camps and were being trained as suicide bombers, fighters and thieves, said Issa Tchiroma Bakary. Joint forces from Cameroon, Nigeria, Chad and Benin carried out the sweep Nov. 27 to Nov. 29, he said.
Troops also arrested 100 fighters, including a group leader, from Boko Haram's strongholds in the Sambisa Forest, which straddles northeastern Nigeria and Cameroon, and in the Lake Chad area, Bakary said.
The freed are being reunited with their families, he said. Trauma care is available for those who need it, including young girls and women who might have been used as sex slaves, he said.
Nigerian troops have rescued hundreds of Boko Haram captives this year but none of the 219 girls kidnapped from a school in Chibok town. Their mass abduction in April 2014 sparked international outrage against the extremists and Nigeria's government for failing to rescue them.
Boko Haram's 6-year-old Islamic uprising has killed an estimated 20,000 people and driven 2.3 million from their homes, according to Amnesty International and the United Nations.
The militants have expanded attacks into Cameroon, Chad and Niger -- countries contributing troops to a regional force intended to wipe out the extremists.
Two teen female suicide bombers detonated explosives late Tuesday in the north Cameroon town Waza, killing six people, Cameroon's Far North province governor, Midjiyawa Bakary, said Wednesday. Soldiers killed a third suicide bomber before she could attack, he said.
Boko Haram has also been planting land mines in north Cameroon, said senior military official Col. Jacob Kodji. Two Cameroonian soldiers were killed Monday by a land mine in Gangse village, he said.
Boko Haram was believed to have been wiped out in northeastern Nigeria in 2009, an area that has been a hotbed of tension for a country that is about half Muslim and half Christian. Instead, they have grown with a vengeance, killing an estimated 20,000 in their 6-year-old uprising, in addition to displacing some 2.3 million people in an area that crosses several international borders.
In November, a report by The Global Terrorism Index detailed how Boko Haram, not ISIS, is the deadliest terrorist group in the world.
The Global Terrorism Index says deaths attributed to Boko Haram increased by 317 percent in 2014 to 6,644 compared to 6,073 blamed on Islamic State. Boko Haram pledged allegiance to ISIS in March and calls itself that group's West Africa Province.
