SAN CRISTOBAL DE LAS CASAS, MEXICO -- Three people were killed and seven others wounded Friday when unknown assailants opened fire on a truckload of undocumented immigrants in the southern Mexican state of Chiapas.
Efe confirmed the presence of two bodies at the scene of the shooting, while sources at the Regional Hospital in San Cristobal de las Casas said that a third person died in an ambulance en route to the facility.
The attack place in Carmen Arcotete, a small community some 5 kilometers (3 miles) from this city.
The wounded include people from Ecuador and China as well as from Mexico's Central American neighbors, according to doctors at the Regional Hospital.
Witnesses said the shooting occurred as the migrant-laden truck was being pursued by local police, but they did not identify police as the shooters.
Residents of Carmen Arcotete said that many of the 30 or so people aboard the truck took off on foot after the attack.
Chiapas, bordering Guatemala, is the gateway for the estimated 300,000 undocumented migrants annually who enter Mexico from Central America by land with hopes of reaching the United States, many of them conducted across the border by people traffickers charging stiff fees.
