Suspected sabotage by Maoist rebels has derailed an overnight passenger train that was then hit by a freight train in eastern India, killing at least 65 people and injuring an additional 200.
The passenger train was travelling from Calcutta to the city of Kurla when 13 cars derailed in the rural part of West Bengal state, about 90 miles west of Calcutta. A freight train then slammed into three of the carriages from the other direction, railway minister Mamata Banerjee said.
Ms Banerjee said the crash was caused by a bomb planted by suspected Maoist rebels.
AP Mishra, general manager of the railway system in that area, said the train had been derailed by a bomb and that the rail tracks had also been sabotaged.
Surojit Kar Purkayastha, a state inspector-general of police, said rebels may have removed part of the track.
Rescuers at the scene used gas cutters to free passengers trapped in mangled coaches.
Medics brought at least 30 bodies to a nearby railway hospital in the town of Kharagpur, said E Mitra, a doctor at the hospital.
The derailment took place in an isolated, rural stronghold of India's Maoist rebels, known as Naxalites, who have stepped up attacks in recent months and had called for a four-day general strike starting on Friday.
Earlier this month, the rebels ambushed a bus in central India, killing 31 police officers and civilians.
The rebels, who have tapped into the rural poor's growing anger at being left out of the country's economic gains, are now present in 20 of the country's 28 states and have an estimated 10,000 to 20,000 fighters, according to the home ministry.
