In the first attack, a suicide bomber detonated his explosives at Tashar Gandu bus station on the outskirts of the town of Biu in northeast Nigerian Borno state, killing 18 people and injuring six others.
A second bomber was mobbed and killed before he could detonate his explosives at the scene of the carnage, residents and local vigilantes said.
“We have received 18 dead bodies from the scene of the suicide explosion along with six injured victims,” said a nurse at the Biu General Hospital who asked not to be named to protect her safety.
Although no one has claimed responsibility for the attacks, Boko Haram Islamists, who have carried out deadly bombings in Biu and Jos, are the prime suspects.
The Islamists are believed to be behind a recent spate of suicide bombings and attacks in parts of the north in response to a sweeping offensive on Boko Haram strongholds in northeast Nigeria by a regional alliance of troops from Chad, Cameroon, Niger and Nigeria.
