Military officials in Ivory Coast say gunmen have attacked a border post on the country's western frontier with Liberia.
Officials say the attacks took place Monday near the town of Toulepleu. Residents in Toulepleu told VOA that most people fled the town following the clash.
Ivorian officials did not say if there were any causalities during Monday's fighting.
The attack follows another one in the border region in June that left seven U.N. peacekeepers dead.
Also last week, gunmen attacked Ivorian soldiers in the main commercial city of Abidjan, killing at least 11 of them.
It is not clear who is behind the attacks.
Officials have blamed them on rouge soldiers and militia still loyal to former president Laurent Gbagbo.
Mr. Gbagbo is currently awaiting trial in the International Criminal Court on war crimes charges stemming from violence after he lost the 2010 presidential election.
