One passenger was killed when a train was blown up while those on a bus miraculously escaped a gun attack and a 20 kg bomb was defused at a SAIL iron mine, police in Jharkhand said on Friday as Maoist guerrillas enforced a 24-hour strike in the state.

The trouble started Thursday night at 9.30 when the Tatanagar-Bilaspur passenger train was blown up as it was passing through a forest in West Singhbhum district. One passenger was killed and 25 injured in the attack that derailed six coaches of the train.
