India has seen a terrifying increase in coronavirus cases in the past few weeks. Monday saw another new record when the country racked up 273,810 new cases, with no sign that the surge is abating.
The capital, New Delhi, was placed in lockdown for a week from Monday, and Maharashtra state, the centre of the surge and home to the financial capital, Mumbai, further tightened restrictions on shops and home deliveries from Tuesday.
The US Centers for Disease Control on Monday advised against all travel to India, and the UK imposed restrictions on arrivals from the country.
India has recorded more than 15m cases of Covid-19, second only to the US, and has the fourth highest death toll at more than 180,000.
