Acharya, who was at Ranaghat in Nadia district in connection with a programme, said he received news of the insurgent attack that left scores dead.
"Some of the victims were poor and innocent people from Jharkhand. It is a very painful incident," he said.
"I am leaving for Assam very today. Meanwhile, I have talked to various levels of administration in Assam. The Central Government has been trying to stop the insurgency problem," Acharya said.
But he cancelled the plan and left for Assam.
