NEW DELHI - At least six people were killed from Monday to Tuesday morning by cold weather in the northern Indian state of Uttar Pradesh, said local media.

All the deaths were reported from Poorvanchal district of the eastern part of the state, where low temperature plus heavy fog descended since early this week, said Indo-Asian News Service.

However, the report did not give specific conditions in which the people have died.

The cold weather was causing revised school timings, poor visibility on the road as well as traffic and train delays, said the report.

Northern India has entered winter season with low temperature and sometimes abnormal weather phenomena.
