Crematoriums in Delhi are being inundated with so many bodies that they have been forced to build makeshift funeral pyres on spare patches of land as the Covid crisis sweeping India led to an explosion of new cases. Crematoriums across the capital are struggling to cope, with grieving relatives forced to wait up to 20 hours for a funeral pyre for their loved ones.

A second wave of the virus is ravaging parts of India, with 386,452 new cases reported on Friday - the biggest one-day increase on record for any country. There were another 3,500 deaths nationwide and nearly 400 in Delhi - a record for the capital. The total number of infections in the country has now passed 20 million.
