Vehicles and passengers along the Enugu Abakaliki expressway were forced to halt movement after unknown gunmen opened fire at the Ezilo axis of the highway.
It was not immediately clear those responsible for the shootings, TheNation reports.
Governor David Umahi had on Tuesday confirmed the killing of two persons in a renewed boundary dispute between Exilic community and the neighboring Iyionu community.
However, it could not be immediately established if the shooting is connected with the dispute.
A passenger from Afam Cyprian, who was travelling to Enugu, said travellers had been stranded at Okpoto for about one hour.
He added that soldiers patrolling the highway had told them not to advance.
“Many people are looking for another route to take. Some have gone back to take Afikpo Road. I am looking for a way to go back to Abakaliki,” he said.
Confirming the shooting, Police spokesperson, Loveth Odah, said the police commissioner, Aliyu Garba has dispatched police patrol teams to restore peace and open up the road for users.
She however said the shooting could not have been related to the boundary dispute as the disputed area is not close to the highway.
