MEXICO CITY - Prosecutors in the Mexican state of Morelos say gunmen have killed five men at a bus station in the capital of Cuernavaca.

The Morelos state prosecutors office says a sixth man was wounded in the attack. Authorities said in a statement Monday the victims were specifically targeted around 4:40 a.m., but did not offer any possible motive.

Multiple organized crime groups maintain a presence in the city 35 miles (56 kilometres) south of Mexico City.

In May, a union official accompanying protesting street vendors was shot to death outside city hall along with another trade unionist.
