India's capital, Delhi, has announced a week-long lockdown after a record spike in cases overwhelmed the city's healthcare system.
Government offices and essential services, such as hospitals, pharmacies and grocers, will be open during the lockdown.
The city had imposed a weekend curfew but reported its highest single-day spike so far on Sunday - 24,462 cases.
India has been reeling from a deadly second wave since the start of April.
Delhi Chief Minister Arvind Kejriwal said the city had almost run out of beds at hospital intensive care units and that oxygen was in short supply.
