Delhi Environment Minister Gopal Rai on Monday said the ban on construction and the entry of trucks, barring CNG, e-trucks and those engaged in essential services, will continue till further orders in view of a forecast about further deterioration of air quality in the national capital.

The government will review the construction ban on December 16, Rai told reporters after a meeting with officials of departments concerned.

The minister said the education department has sent a proposal to the environment department, seeking immediate reopening of schools and coaching centres for students in Class 6 and above, and in colleges.

For children of Class 5 and below, the education department has suggested reopening schools from December 20, he said.

The proposal will be sent to the Commission for Air Quality Management (CAQM), which has been mandated by the Supreme Court to take a call on the reopening of schools and colleges, Rai said.
