More than 400 people have died in the southern Pakistani city of Karachi due to a devastating heatwave that has continued over three days.
Temperatures reached a high of 44 degrees Celsius, about seven degrees higher than typical summer temperatures in the port city, home to 20 million people.
Pakistan's paramilitary Rangers force has set up medical camps at several points in Karachi where they are providing water and anti-dehydration salts.
Meteorological authorities say rain is due.
