NEW DELHI, Nov. 11 (Xinhua) -- As the killer haze continued to envelope the Indian capital for the fifth day in a row, train services were severely affected Saturday.
Indian Railway officials said that as many as 80 trains have been hit due to smog.
"While 64 trains running to and from Delhi were delayed, 14 have been rescheduled and two were cancelled because of low visibility on tracks owing to smog," a senior railway official said.
According to India's Central Pollution Control Board officials, air quality continued to remain in the "severe" zone in Delhi.
All schools in the national capital have been shut till Sunday because of the prevailing weather conditions and heavy vehicles banned to reduce vehicular emission.
Delhi Chief Minister Arvind Kejriwal has urged his counterparts in the northern states of Punjab and Haryana to immediately stop stubble burning.
Stubble burning by farmers in these two states every year is one of the main causes of high pollution levels in the Indian capital.
Despite the country's top green court putting a ban on such activity, the practice continues.
