LAGOS, Feb. 17 (Xinhua) -- A suspected suicide bomber detonated his explosive in the midst of 13 trucks along Maiduguri/Mafa road in northeast Nigeria's Borno State, police said Friday.
State police spokesperson Victor Isuku said in a statement in Maiduguri, the state capital, that only the bomber was killed as the vehicles were parked empty.
A police patrol team was promptly deployed to the scene to restore safety and normalcy, the police spokesman said.
This came barely 24 hours after the Nigerian Air Force (NAF) said its helicopter conveying personnel on medical outreach program at Gwoza came under attack by the insurgents.
The Mi-17 helicopter was shot at several times by the insurgents. However, there was no casualty except for an airman that sustained bullet wound.
The helicopter had departed from Maiduguri en-route the venue of the 2-day medical outreach program in Gwoza when it came under attack by the insurgents.
The Nigerian Air Force has been conducting medical outreach in the North-East as part of its humanitarian support to Internally Displaced Persons (IDPs).
The latest of this effort was in Gwoza, followed by a similar effort undertaken recently for IDPs in Lagos area.
