ABUJA, May 15 (Xinhua) -- Five members of a local vigilance group were killed Tuesday afternoon in a blast in Nigeria's northeastern town of Konduga, according to the National Emergency Management Agency (NEMA).
Five others were injured in the blast at a checkpoint on the outskirts of Konduga in the northern state of Borno, NEMA said in a statement made available to Xinhua.
The deceased operatives were members of the civilian volunteer force helping the military in the fight against insurgents in Nigeria's northeast, the agency said.
The blast occurred as security operatives stopped the suicide bomber at a military checkpoint at the entrance of Konduga Town.
Konduga, with a population of over 13,000, has witnessed frequent attacks by terror group Boko Haram in Borno. Its inhabitants are mostly engaged in subsistence farming.
In February, at least 22 people were killed and 28 others injured in multiple suicide blasts orchestrated by Boko Haram rebels at a market in Konduga.
Boko Haram has been blamed for the death of more than 20,000 people and displacement of 2.3 million others in Nigeria since 2009.
