New Delhi targets older diesel vehicles to clear up choking smog

By Sanjeev Miglani NEW DELHI (Reuters) - Authorities in New Delhi began revoking licenses for thousands of older diesel vehicles on Tuesday and halted construction work on the underground rail network, as air pollution remained several times over the safety limit. India's Supreme Court, which has in the past led the drive to clean up the city's air, ordered the Delhi administration to report back in two days with a plan to combat the worst smog in 17 years. Licenses given to diesel-powered vehicles more than 15 years old are being withdrawn, which would lead to the removal of 200,000 vehicles from the city's roads, Delhi lieutenant governor Najeeb Jung's office said in a statement earlier in the day.
