India is opening up to fully vaccinated foreign tourists while several European countries enforce tighter COVID-19 restrictions amid rising infection rates.
Tourists entering India must be fully vaccinated, follow all COVID-19 protocols and test negative for the virus within 72 hours of their flight, according to the health ministry.
Many will also need to undergo a post-arrival COVID-19 test at the airport.
However, travellers from countries which have agreements with India for mutual recognition of vaccination certificates, such as the US, UK and many European countries, can leave the airport without undergoing a COVID-19 test.
This is the first time India has allowed foreign tourists on commercial flights to enter the country since March 2020, when it imposed one of the toughest lockdowns in the world in an attempt to contain the pandemic.
Fully vaccinated tourists on chartered flights were allowed to enter starting last month.
It comes as coronavirus infections have fallen significantly, with daily new cases hovering at just above 10,000 for more than a month.
To encourage travellers to visit India, the government plans to issue 500,000 free visas through next March.
The moves are expected to boost the tourism and hospitality sector which was battered by the pandemic.

These measures come as figures have been soaring in Austria, with authorities recording nearly 850 cases per 100,000 people over seven days.
The lockdown measures, in force until November 24, are designed to encourage people to get jabs.
Russian authorities are mulling mandatory health passes to access public spaces and transport.
Russia's COVID-19 information centre on Monday recorded 38,420 new cases within 24 hours, with a death toll topping 1200 for the seventh consecutive day.
Russian authorities blame the sharp increase in infections and deaths on the highly contagious Delta variant as well as a general lack of public compliance to health rules combined with an unwillingness to get vaccinated.
A dramatic increase in numbers of infections in Germany is putting further pressure on the negotiations to form a new coalition government.
