Haitian authorities are investigating a street protest that turned violent in a northeastern town close to the country's border with the Dominican Republic.

Police spokesman Frantz Lerebours says people were wounded by gunfire during a Thursday protest in Fort Liberte but he cannot immediately say how many. He also is giving no details on how they were shot.

Opposition Sen. Jean-Baptiste Bien-Aime from Haiti's northeast area asserts that 13 people were wounded by Haitian police officers who fired their weapons while trying to clear demonstrators from the main road to allow trucks to pass.

Bien-Aime says the protesters were demanding to be supplied with electricity from a power plant at an industrial park in Caracol.

Lerebours says the head of the Haitian police force has sent a team to investigate.
