Abuja, September 1 (RHC)-- Takfiri Boko Haram militants continue their attacks in northeast Nigeria, with four people killed in a raid on the village of Karnuwa.  Another attack was reported in the village of Hambagda, where terrorists killed seven people and injured five others. 

Nigerian President Muhammadu Buhari, who came to power in late May, replaced the heads of the army, navy, air force and his chief of defense staff in an effort to re-energize the fight against Boko Haram. 

The terrorist group has since stepped up its attacks.  According to an AFP count, bombings, a wave of raids and attacks have left at least 1,000 people dead in Nigeria alone in less than three months. 

The Boko Haram militancy began in 2009, when the terrorist group started an armed rebellion against the government of Nigeria.  Amnesty International says 17,000 people have been killed since then. 

The militancy has spilled over into Nigeria’s neighboring countries. Troops from Nigeria, Chad, Cameroon and Niger have been battling the terrorists in recent months. 

Nigeria's neighbors, which have all suffered attacks by Boko Haram, set up a regional force earlier this year to end the conflict.
