The Assam government on Thursday said the banned ULFA may have perpetrated the serial blasts in the state but it was too early to reach a conclusion.
"It is very early to make a conclusion but ULFA has a history of triggering serial blasts," Assam's Health Minister Himanta Biswa Sarma told reporters minutes after the explosions.
Sarma said the objective of the triggering the blasts in the crowded places was to claim more lives.
"Most of the bombs were planted in crowded places like markets and office complexes. So it shows that the perpetrators wanted high casualty," he said.
The Minister said one of the blasts took place close to the state capital complex in Ganeshguri.
