In Usaka Ukwu and Nkaria, two communities on two sides of the Abia and Akwa Ibom border, an unspecified number of persons have been killed in a land tussle.
Usaka Ukwu is in Ikwuano council area of Abia where some accounts claimed that six persons were killed while a larger number of people have been hospitalised in parts of the state.
The clash, which took place on Monday, forced many from their homes, the reporter learned.
Both communities have been at loggerheads over land for years.
It was gathered that the government of the two states have met over the land under contention and were waiting for the National Boundary Commission (NBC) to delineate it.
Police spokesman in Abia Geoffrey Ogbonna told the reporter on the phone that he was yet to receive any recent clash report in the area.
“As a government, we condemn in totality the act of violence. The National Boundary Commission has visited the area and very soon they will delineate the boundaries properly. We are calling on the communities involved to exercise restraint and avoid shedding of blood.”
The President gave the warning while reacting to the killing of 11 persons in Gwer council area of Benue State, as well as the mob action that claimed some lives in Anambra State.
In a statement issued by his Senior Special Assistant on Media and Publicity, Mallam Garba Shehu, the President condemned the two incidents.
“If we allow this culture of violence to go unchecked, such mobs would destroy law and order,” he said.
