Police sources here said the first blast took place in a truck near the Srirampur check gate in Assam's Kokrajhar district at 1000 hrs. The bomb was planted below the oil tank of the truck that was bound for West Bengal. A school teacher was critically injured in the blast. The driver and handyman of the truck, however, escaped unhurt.
The second blast occurred near the same location when a bomb, fixed to a bicycle, went off at about 1130 hrs. The bicycle was parked near a petrol depot and much damage could have been caused had the blast occurred in closer proximity of the depot. Another person was injured.
Police further informed that another bomb has been recovered near the Srirampur check gate. An Army bomb disposal squad has been rushed in to defuse it.
Traffic movement through the inter-state check gate has been halted temporarily to avert any further damage. However, traffic was likely to be opened later in the afternoon.
