Delhi Lt. Governor Najeeb Jung on Monday ordered de-registration of diesel vehicles that are 15 years old or more to battle unprecedented smog levels that have turned the national capital into a virtual gas chamber.

The decision will apply to about two lakh diesel vehicles on Delhi roads, a statement from Jung's office said. 

The Lt. Governor also ordered shutting down of all polluting industries in Delhi.

The decisions were taken at a meeting at the Raj Niwas to discuss the serious air pollution levels in Delhi.

The meeting was attended by Chief Minister Arvind Kejriwal, Deputy Chief Minister Manish Sisodia, Health Minister Satyendar Jain and Environment Minister Imran Hussain, apart from senior government officials.

Environmental experts Sunita Narain and Anumita Roy from Centre for Science and Environment and Prof. Manju Mohan from Indian Institute of Technology-Delhi also participated.
