Near-freezing temperatures and icy Himalayan winds have killed dozens of people in northern India.
In the worst-hit Uttar Pradesh state, five people died from the cold overnight, pushing the number of deaths there to 41.
Uttar Pradesh is one of India's poorest states and nearly a fifth of its 180 million people are homeless.
In New Delhi, at least 10 homeless people have died from the cold weather over the past two weeks despite a drive by police and welfare officials to persuade people living on the streets to sleep in 80 city-run shelters.
All schools in New Delhi have been ordered to close for a week because of the intense cold in the capital.
