As people in Delhi and surrounding areas continue to breath toxic air, a review of air pollution in north India by Cabinet Secretary Rajiv Gauba on Tuesday found that crop stubble burning in Punjab and Haryana still continues.
The states have been asked to take violators to task by imposing penalties.
During the daily review, "it was observed that the cases of crop stubble burning in Punjab and Haryana still continues and that there is a need for more focussed action", a statement from the Prime Minister's Office said.
