Argentina bus and trains crash, killing at least sevenAt least seven people have died in the collision of a bus and two trains in the Argentine capital, Buenos Aires.
At least 160 people were injured, seven seriously, reports said.
The crash happened during the morning rush hour as hundreds of commuters were waiting at the station in Flores, a Buenos Aires suburb.
One train hit the bus that was going through a level crossing near the station, dragging it along the lines and into a second train, police said.
The accident happened at about 07:00 local time (10:00 GMT) on the Sarmiento line, which connects the centre of Buenos Aires with the western suburbs.
Children injured
The impact reduced the bus to a fraction of its width as it became wedged against the station platform, AP reports.
Transport Secretary JP Schiavi said that the bus driver was among those killed.
He said that children were among the injured as many parents use public transportation to take them to school.
Officials are investigating reports that the bus driver did not stop and went through lowered barriers in an attempt to cross the railway line.
Train company spokesman Gustavo Gago said it believed the bus had "crossed on to the level-crossing when the barriers were low, but we await the results of the investigation to see if this is what happened".
A total of 100 ambulances and 10 fire engines were sent to the scene.
A local fire chief confirmed the injured were being taken to local hospitals, some by helicopter.
According to Argentine newspaper Clarin, firefighters took two hours to remove one of the train drivers who was trapped in the wreckage.
