India reported its fourth coronavirus death on Thursday while the total COVID-19 cases rose to 173, as the government banned landing of all international commercial passenger flights from March 22 for a week, and Prime Minister Narendra Modi urged people to stay indoors and called for 'Janata Curfew' on Sunday.

Giving the details of the fourth coronavirus fatality in the country, the Union health ministry said the person, who died in Punjab, was elderly and had co-morbid conditions like diabetes, cardiac ailments. There were more than 20 fresh cases in the last 24 hours with Chhattisgarh and Chandigarh reporting their first COVID-19 patients on early Thursday.

Making a fervent appeal to all Indians to stay indoors and only go out of homes if it was extremely, he asked them to observe 'Janata curfew' on March 22 from 7 am-9 pm and also express gratitude for those working in hospitals, airports and other places without worrying about themselves.

"On March 22, at 5 pm on our doors, balconies or wherever, for 5 minutes, express our gratitude for these workers. By clapping, by ringing a bell. I request local admin to blow a siren to inform everyone about this," Modi said during his nearly 30-minute address. He asserted that the experience and success of Janta Curfew' will also prepare the nation to face challenges in the future.
