The six injured soldiers are critical, the police said.

The 52-seater bus was part of a convoy that was on way for the BSF's induction for deployment in the next phase of the assembly election, the police said.

A total of 35 BSF soldiers were travelling in the seven-bus convoy.

The bus went off the hilly road and fell 40 feet on its side, the police said.

All the injured BSF personnel are being treated in a hospital.
