NEW DELHI (AP) — Railway officials say two explosions on a train have killed one woman in a southern Indian railway station and wounded another nine people, including two seriously.

Chief spokesman of India’s southern railway system M. Bhupati said Thursday that authorities suspect the blasts were caused by bombs planted on the train. Police are investigating.

Bhupati says at least one of the blasts erupted from underneath a seat on the Bangalore-Guwahati Express after it had pulled into the station in the south-coast city of Chennai on Thursday morning. The woman killed had been sitting in the seat where the explosion occurred.

He says two of the injured are being treated in a hospital for serious injuries.
