India has embarked on a “massive” operation involving naval ships and aircraft to bring back some of the hundreds of thousands of nationals stuck abroad due to coronavirus restrictions, the government said. India banned all incoming international flights in late March as it imposed one of the world’s strictest virus lockdowns, leaving vast numbers of workers and students stranded. Hong Kong announced plans to ease major social distancing measures, including reopening schools, cinemas, bars and beauty parlours after the Chinese territory largely halted local transmission of the deadly coronavirus.
