A person was killed and 10 others were critically injured in an bomb attack by suspected ULFA cadres in a market near the Dispur capital complex in Guwahati on Wednesday.
The bomb, kept in the Ganeshguri wholesale vegetable market, exploded at around 6.50 pm, police said.
The injured were rushed to a nearby hospital.
The market is located near the Indian Airlines office adjacent to a high-security complex where the offices of the chief minister and his cabinet colleagues as well as the state secretariat are located.
The blast took place a day after Prime Minister Manmohan Singh delivered a tough message to ULFA militants that there would be no compromise if they resorted to violence and assured foolproof security to Hindi-speaking people, 70 of whom were gunned down recently by the banned group.
The army launched a major offensive against the ULFA in Assam and Arunachal Pradesh in the wake of the killings.
