DIBRUGARH, India -- No one had taken responsibility for a bomb that went off beneath a passenger train in India Thursday, killing five people and injuring several others.
The blast occurred shortly before 1:30 a.m. in India's northeastern state of Assam, the BBC reported. The train had left Dibrugarh and was headed for the state capital of Guwahati and New Delhi, the British network said.
North-East Frontier Railway spokesman Trikhal Rabha told the BBC it was fortunate the bomb exploded beneath a car that primarily held parcels and space for only a few people.
Authorities investigating the attack said it appeared the explosives were planted on the railroad tracks and left a deep crater.
"It appears the explosive was planted on the track but we need more investigation to establish that," Assam police intelligence chief Khagen Sarmah said.
None of the several insurgent groups active in Assam had claimed responsibility for the blast, the BBC said.
On Monday, a Delhi-bound passenger train carrying a large number of Indian soldiers was derailed in the neighboring state of West Bengal, resulting in one death and several people injured. Sabotage had not been not ruled out in that incident.
