Four people have died while travelling on a non air-conditioned train during a summer heatwave in India.
Officials said the four people, who were between 69 and 81 years old, were part of a group returning from a Hindu pilgrimage to the southern state of Kerala.
It came as temperatures reached 48C.
Railway official Manoj Kumar said they had been visiting the holy city of Varanasi in northern India.
Mr Kumar said they fell sick in their coach and the doctors who attended to them at Jhansi station found them dead.
Travelling in air-conditioned coaches is too expensive for many poorer Indians.
Schools and colleges were closed due to the heat wave, with people advised to stay indoors during daytime.
The highest ever recorded temperature, according to Guinesss World Records, is 56.7C: recorded in California in 1913.
