Spokesman for the National Emergency Management Agency, Yushua Shuaib said the overnight bomb blast occurred in Jalingo town in Taraba state.
He said a similar blast in the town had killed one person and left 14 others wounded on Thursday.
Though no group has claimed responsibility, the only terrorist group that has been carrying out such bombing campaigns in the country is the Islamic sect known as Boko Haram.
The group wants an Islamic state in Nigeria's mostly Muslim north.
More than 1,000 people have been killed in the north and capital city of Abuja since the sect started bombing and shooting at people in public places since 2009.
