A massive fire broke out in the state-of-the-art hydrocracker unit of Numaligarh refinery in upper Assam's Golaghat district on Saturday night following an explosion. The Paresh Barua-led faction of the United Liberation Front of Asom claimed responsibility.

The incident coincided with the observance of the raising day by both factions of the ULFA.

However, the police said the refinery authorities believe it to be an industrial accident.

In a statement e-mailed to a section of media, the Paresh Barua-led faction of the ULFA claimed responsibility for the attack and claimed it used Magnetic Time Device to trigger the blast.
