A high-level central team comprising senior Home Ministry officials will visit Assam to make an on-the-spot assessment of the situation arising out of serial blasts in the state.
Union Home Secretary Madhukar Gupta told PTI that an NSG team will also visit the spots of the serial blasts.
When asked about the nature of the explosives used, he said forensic experts were already examining the blasts sites.
On whether additional para-military forces would be sent to the state, he said there were enough forces already deployed there.
"We will retain them for some more time and probably not deploy them on poll duties (in six states)," he said.
When asked about who could be behind the blasts, he said it was too early to identify the group.
At least 40 people were killed and more than 200 injured in 13 serial bomb blasts in Assam.
