At least 43 people were killed in India's capital New Delhi after a fire hit a factory where workers were sleeping, police said.
Another 16 people were being treated for burns or smoke inhalation and more than 50 people were transferred to safety, a Delhi Fire Department official said.
The fire began around 5:30 am on Sunday in the six-story building in a busy residential area.
The factory was producing bags and much raw material was stored inside the building, causing the fire to spread rapidly, local media reported.
However, no details were immediately available on the cause of the fire.
More than 50 people were rescued
India's Prime Minister Narendra Modi described the fire as "extremely horrible".
"My thoughts are with those who have lost their loved ones. Wishing the wounded a speedy recovery," Modi tweeted.
Authorities are providing all possible assistance at the scene of the tragedy, he said.
Fires are common in India, where building laws and safety standards are often disregarded by builders and residents.
In 1997, a movie fire in New Delhi killed 59 people.
In February this year, 17 people were killed by a fire in a six-story hotel, also in the Indian capital, which began in an unauthorized rooftop kitchen.
