A Nigerian soldier was gunned down in Etekuru, Ohaji Egbema Local Government Area of Imo State.
The personnel rifle was also stolen, according to reports.
In a reprisal, however, soldiers sacked the community burning down houses.
About two weeks ago, two soldiers in Izombe in Oguta Local Government Area of the state were killed, leading to reprisal by soldiers who burnt down houses in the community.
The tension in Imo is a follow up to the killing of two traditional rulers in neighbouring Okwudor on Tuesday.
The tension peaked into clashes between some youth and security agents as the community observed the sit-at-home ordered by the Indigenous Peoples of Biafra IPOB) following Thursday’s arraignment of their leader, Nnsmdi Kanu.
Fatality figures could not be ascertained but the town has been deserted as many have fled their homes.
There was no immediate reaction of Army spokesperson in the area, Capt. Joseph Akubo
