LORCA, Spain (AP) _ A commuter train slammed into a van carrying Ecuadorean farm workers and dragged it 200 yards Wednesday, killing at least 12 of the immigrants, authorities said.

Another two Ecuadoreans were hospitalized in critical condition after the early morning accident at a rail crossing in southeast Murcia province outside the town of Lorca. Several people aboard the train suffered slight injuries.

The three-car commuter train derailed after hitting the van, Jose Joaquin Penarrubia, the Interior Ministry representative in Murcia, told Spanish National Radio.

The radio and Spanish news agencies said bodies were strewn along a 200-yards stretch of rail line as the train pushed the van, breaking it to pieces as it moved.

The train was carrying about 30 people, several of whom suffered slight injuries, Lorca town hall spokesman Tomas Guillen said.

The rail crossing was clearly marked but had no barriers.

Ecuadoreans are one of Spain's largest immigrant communities. In Lorca alone there are 5,000 to 6,000 working on farms that grow vegetables such as tomatoes, artichokes, broccoli and lettuce, Guillen said.
