Two persons were killed and eights others injured in fresh violence and exchange of fire between anti-land acquisition Bhumi Ucched Pratirodh Committee and Communist Party of India-M supporters in Nandigram on Tuesday.
The two sides exchanged several rounds of fire since early on Tuesday at Gokulnagar, Ranichak, Bhangaberia and Satengabari areas with the violence still continuing, West Bengal Home Secretary P R Roy said in Kolkata.
An Eastern Frontier Rifles personnel was among the injured.
The EFR was controlling the vital Tekhalibazar bridge linking Sonachura and Nandigram, he said.
Asked if the state government was contemplating police action to tackle the situation, Roy said, "Let's see".
"The police came under fire when they tried to intervene," East Midnapore Superintendent of Police S Panda told reporters.
Following the clashes there was an exodus from Satengabari and Ranichak villages.
