Indian Prime Minister Narendra Modi's home region Gujarat became the latest to tighten coronavirus curbs as the country's infections surged to a record of almost 116,000 new cases in 24 hours.
Experts blame the country's fresh wave on people ignoring guidelines and attending huge religious and political events, as well as weddings and cricket matches, according to Reuters.
India has now recorded 12.8 million cases, the third-highest behind the United States and Brazil, although those nations have much smaller populations. More than 166,000 Indians have died.
Maharashtra, the worst-hit state and home to megacity Mumbai, has imposed a night curfew and weekend lockdowns are due to begin on Friday evening.
