Tens of thousands of Hindu pilgrims have gathered in the northern Indian city of Prayagraj (formerly Allahabad) for a festival amid a massive surge in Covid-19 infections.
Devotees believe that bathing in the river Ganges during the Makar Sankranti festival would cleanse their sins.
A similar gathering had contributed to India's deadly second wave last year.
But the authorities in Uttar Pradesh state, where Prayagraj is located, have refused to ban this year's event.
