A new report from Amnesty International has claimed that the Boko Haram militant group killed at least 381 civilians in Cameroon and Nigeria over the past five months.
The report claims that several attacks and suicide bombings have taken place since April.
Amnesty found that the increase in civilian deaths in the Far North region of Cameroon and the Nigerian states of Borno and Adamawa is due the increased use of suicide bombers by the armed group.
Boko Haram forces women and girls to carry explosives into crowded areas, Amnesty stated.
Amnesty International West and Central Africa director Alioune Tine said: “Boko Haram is once again committing war crimes on a huge scale, exemplified by the depravity of forcing young girls to carry explosives with the sole intention of killing as many people as they possibly can.
“This wave of shocking Boko Haram violence, propelled by a sharp rise in suicide bombings, highlights the urgent need for protection and assistance for millions of civilians in the Lake Chad region. Governments in Nigeria, Cameroon and beyond must take swift action to protect them from this campaign of terror.”
During the investigation, the human rights organisation analysed media reports of Boko Haram attacks and casualties and found that 100 civilians were killed in August alone.
Boko Haram abducted 67 people, mostly women and girls, since the beginning of this year.
The displacement of Boko Haram fighters from the Sambisa Forest in Nigeria to the Mandara Mountains in Cameroon might have contributed to the increase in attacks in Cameroon.
