India has reported its biggest single-day jump in new coronavirus cases, with 601 in the past day representing a 26% rise, according to the Ministry of Health and Family Welfare.

The country now has 3,082 cases and 86 deaths, according to figures from Johns Hopkins University.

The surge in cases has been linked to a religious gathering held at a New Delhi mosque in March, a senior health ministry official said. People from across India and overseas had gathered for the event.

So far, 647 cases have been directly linked to the gathering, said Lav Agarwal, a senior official of the Ministry of Health and Family Welfare. He added that the cases have been identified and isolated across 14 states and union territories

The Delhi government said earlier this week that it will be taking strict action against those responsible for organizing the gathering.
