Nigerian officials said multiple suicide blasts near the northern city of Maiduguri have killed at least 15 people and seriously wounded five soldiers.
The attack Tuesday involved four cars packed with explosives. Officials said two of the drivers rammed their vehicles into a major military checkpoint, setting off explosions.
Security forces killed the other two drivers before they could detonate their bombs.
The police commissioner of Nigeria's Borno state said the attack appeared to be the work of Islamist militant group Boko Haram.
The group is blamed for thousands of deaths since 2009. Amnesty International said Monday that 1,500 people have died in Boko Haram-related violence this year alone.
