The Maiduguri-Biu highway has been one of the most dangerous routes in northeastern Nigeria for three years because of Boko Haram attacks. The Nigeria military recaptured it last year and declared it safe, but the military escorts motorists moving in convoy along the road.
Eyewitness, Dauda Pambe, said he was among the travelers guarded by soldiers when gunmen launched the ambush attack yesterday.
"We were somewhere between Bulabulin and Dogonwaya villages when the Boko Haram gunmen opened fire on the vehicles ahead of us in the convoy," said Pambe.
The gun fight continued for some time with many passengers ducking in their vehicles to avoid being hit by bullets, said Pambe.
The incident came three days after Boko Haram gunmen suffered a heavy loss of members after a foiled attempt to attack a military base in Borno state. In that incident, a large number of the insurgents stormed a military base in Kamaya but failed to dislodge the soldiers.
