Blasts kill four, injure 18 in Nigeria

Multiple blasts have killed four people and injured eight others in the northeastern Nigeria city of Maiduguri, the state police commissioner says.

Borno Police Commissioner Damian Chukwu said three blasts occurred near the Muna Garage area of Maiduguri, the city worst hit by an eight-year-old insurgency by Islamist Boko Haram militants, early on Wednesday.

"Three bomb explosions occurred this morning at three different locations near Muna Garage, Maiduguri. Four people were killed and 18 people injured," he said.

Chukwu said two of the blasts happened at camps for people displaced by Boko Haram. The frequency of attacks has increased since the end of the rainy season in late 2016.

Maiduguri has been the city worst hit by Boko Haram's eight-year-old campaign to create an Islamic caliphate in northeastern Nigeria. Its attacks have killed about 15,000 people and forced more than two million to flee their homes.
