Four suicide bombers on motorcycles killed at least 23 people and wounded more than 100 others in Chad’s capital on Monday, raising fears of a widening threat from the Islamist militant group Boko Haram.
There was no immediate claim of responsibility for the simultaneous attacks on two buildings, including the national police academy, in N’Djamena. But suspicion quickly fell on Boko Haram, the Islamist group based in northeast Nigeria.
The suicide attacks were the first of their kind in the capital of an ally of Nigeria involved in the fight against the group. In recent months, its strongholds in Nigeria have come under increased pressure from a five-nation coalition of African forces.
