TEHRAN, Iran -- A heat wave blanketing Iran has forced authorities to cut operating hours at various facilities Saturday and order all government and commercial institutions to shutter the following day as hospitals receive over 200 people for heatstroke treatment.

The temperature ranged from 37 degrees Celsius (98.6 degrees Fahrenheit) to 42 C (about 107 F) in the capital, Tehran, according to weather reports.

State-run IRNA news agency said banks, offices, and public institutions across the country would close on Sunday to protect people’s health and conserve energy, due to extreme temperatures and that only emergency services and medical agencies would be excluded.

Babak Yektaparast, Spokesman for the country’s emergency department told the semi-official Mehr news agency 225 people had to seek medical help for heatstroke, adding that some had to be hospitalized.
