Police say a late-night attack and subsequent counterattack left six people dead in a quiet central Nigerian town.
Benue State police spokesman Ejike Alaribe told The Associated Press on Tuesday that a prominent opposition politician was killed with his cousin Sunday night in the town of Ugba.
The opposition party identified them as Celestine Ahemba and Shangev Orayor in a press statement.
Alaribe says a mob angered by the politician's death killed four others in the town Monday and torched several houses.
State government spokesman Conrad Wergba said all four were killed in the compound of a local traditional ruler believed to support of the ruling party.
The spate of violence comes as Africa's most populous nation readies for local elections.
