At least four passengers were killed and 23 others injured when 12 coaches of the Dibrugarh-bound Rajdhani Express derailed near Chapra in Bihar's Saran district, with a controversy arising whether the Maoists had a hand in it.
Railway Minister Sadananda Gowda after inspecting the accident spot said that the sabotage angle and its denial would both be considered during investigation.
Gowda announced ex-gratia of Rs 2 lakh for the family of each of the dead, Rs one lakh for the grievously injured passengers and Rs 20,000 for those with minor injuries.
Union Home Minister Rajnath Singh said it was too early to blame the Maoists for the accident.
