At least 17 people died and 21 were injured suicide blasts in the northeast Nigerian city of Maiduguri, the Borno state police commissioner said on Wednesday.
This was the latest in a spate of suicide bomb attacks on the city over the last few weeks. Borno, of which Maiduguri is the capital, is the Nigerian state worst affected by the insurgency by the Daesh-affiliated Boko Haram.
Witnesses said four suicide bombers carried out attacks in Molai district, which is around five kilometres from the city centre, on Tuesday night at around 10 pm (2100 GMT). Nobody has claimed responsibility for the attacks.
Borno police commissioner Damian Chukwu said the four suicide bombers were among the 17 killed.
Boko Haram has killed more than 20,000 people and forced some 2.7 million people to flee their homes and has been leading a nine-year-long insurgency against the governments of Nigeria, Niger, Cameroon and Chad.
The group has been pushed out of most of a swathe of land around the size of Belgium that it controlled in early 2015 by Nigeria’s army and troops from neighbouring countries in northeast Nigeria.
But insurgents continue to carry out suicide bombings and raids in northeast Nigeria, as well as in Cameroon and Niger.
