"It is a very unfortunate incident and in the run up to the polls, in many places like Chhattisgarh and Jharkhand, a lot of precautions are to be taken by the polling staff when they go to the polling station," Sampath told reporters here, replying to a query.
"There have been two such incidents today, where there were some casualties. We are yet to get full details. All the injured people have been taken to hospital. The Commission will do everything to stand by the families of those who were injured or have been killed," he said after taking stock of the preparations in Tamil Nadu that would go to poll on April 24.
Eleven persons, including five paramilitary personnel, were also injured in the incidents.
