Seven people were killed and 20 injured in a blast which took place at a displaced people camp in the northeast Nigeria, the main relief agency in the country said on Friday.
The explosion took place after a homemade bomb planted in one of the tents exploded shortly before 11:00am (1000 GMT) at the Malkohi internally displaced persons (IDP) camp near the Adamawa state capital, Yola. The camp is for people displaced due to the conflict with Boko Haram in the country.
"So far seven persons lost their lives and 20 persons were injured in the bomb blast," a spokesman for the National Emergency Management Agency [NEMA], Sani Datti, said in a statement on Friday.
No one immediately claimed responsibility for the attack but the main suspect is Boko Haram, which often launches attacks targeting civilians.
Militants belonging to Boko Haram - which has announced its allegiance to ISIS - occupied an area the size of Belgium in Nigeria last year.
The militants have been fighting a six-year insurgency responsible for the deaths of over 30,000 civilians and security personnel, causing about 1.5 million people to flee their homes, in a bid to establish a state of its own in northern Nigeria.
Nigeria - alongside military coalition partners Niger, Chad and Cameroon - has claimed successes in fighting Boko Haram since February, forcing the group’s fighters out of the territory it used to control.
The recent attacks carried by Boko Haram have caused a humanitarian in Africa's Lake Chad region. According to the World Food Programme (WFP), in some areas malnutrition is at "catastrophic" levels.
It is reported that $16.3 million is needed to provide the needs of the hundreds of thousands of people who have been displaced and three quarters of a million are going hungry in Chad, Niger and Cameroon.
