Kolkata, June 27 : A person was killed and four others were severely injured following clashes and gun-battle between Trinamool Congress and BJP supporters early on Tuesday in Cooch Behar district over the West Bengal panchayat polls.

The clash was the latest in a series of violent incidents in the run up to the polls. At least 11 people have been killed and dozens injured in clashes since June 8 when the State Election Commission (SEC) announced the poll schedule.  “A political clash broke out between two groups. Seven persons sustained bullet injuries out of which one died. He has been identified as Babu Haque,” said a police officer posted in Cooch Behar, requesting anonymity.  The fresh clash scene is close to the unfenced portion of the India-Bangladesh border. “There is a probability that Bangladeshi criminals might have been used by local leaders in the incident,” said a second police officer. “Further investigation is going on.”
