Another OIL pipeline was damaged at Lerelapathar near Rajgarh when an improvised explosive device fitted to it went off at 8 pm.
The orgy of violence started in the state capital with suspected Ulfa rebels lobbing a grenade from the Ganeshguri flyover around 6.50 pm. The grenade exploded at the entrance to Hotel Ambarish. The police said 12 people were injured in the blast, the fourth in Ganeshguri in the past one year.

Five more, including a six-year-old boy, suffered minor injuries and were released from hospital after first aid.
The convoy of the GOC of the Tezpur-based 4 Corps, Lt Gen. H.S. Liddar, had crossed the flyover minutes before the blast. The army official met the governor, Lt Gen. (retd) Ajai Singh, at Raj Bhavan this evening.
