Multiple blasts killed four people and injured eight others in the northeastern Nigeria city of Maiduguri, the state police commissioner said on Wednesday.
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, at around 04:30 a.m. (0330 GMT).
Over the past seven years, Boko Haram violence has displaced more than 2 million people and killed at least 20,000, according the United Nations.
The militant group has recently stepped up attacks after a lull that lasted months due to a leadership struggle.
Since Boko Haram first took up arms against the Nigerian government in 2009, trade routes and farming activity have been disrupted.
Although Nigerian President Muhammadu Buhari has led a successful military campaign against the militant group since he assumed office, Boko Haram is still capable of executing deadly attacks.
The violence is not limited to northeastern Nigeria and has spilled over into Niger, Chad and Cameroon.
