Twin bomb blasts hit Indian train

At least five people have been killed and 40 injured after two bombs exploded on a passenger train in the Indian state of West Bengal.

The blasts ripped apart two carriages of the Haldibari passenger train near Belakova village, in north-west Bengal.

Police say some passengers are trapped in the wreckage. It is not yet clear who was responsible for the attack.

However, police say they suspect the involvement of separatist groups active in West Bengal and Assam.

Railway officials said the two carriages were to be joined with another train - the Darjeeling Mail, which links northern West Bengal with the capital, Calcutta.

They said the blast took place just before the carriages were to be connected.

This is the first major explosion in this area since 1999, when a blast hit a military train carrying Indian soldiers to the Kargil front in Kashmir. Ten soldiers were killed in the attack
