Lagos, Nigeria (CNN) -- Suicide bombers suspected to belong to a militant Islamist group targeted a military base in northeastern Nigeria on Friday. No one was killed.
Three suicide bombers drove a black SUV, reported stolen the day before, toward a Joint Task Force headquarters in Maiduguri but could not get through the gate, military spokesman Lt. Col. Hassan Mohammed said.
The blast damaged roofs and walls of the base.
Mohammed said two other simultaneous explosions took place at other military facilities. An unspecified number of Nigerian soldiers suffered "minor injuries."
He blamed the militant group Boko Haram for the attacks.
Loosely translated, the group's name means "Western education is sinful." It wants to establish a state based on Sharia law, or Islamic law, in northern Nigeria.
Authorities have blamed the group for previous shootings and bombings around Maiduguri.
In August, Boko Haram claimed responsibility for a suicide car bombing of the United Nations headquarters in Nigeria's capital Abuja, which killed at least 23 people.
The group said U.N. was a partner "in the oppression of believers."
