India's daily coronavirus death toll has passed a new record as the government battled to get oxygen supplies to hospitals overwhelmed by the hundreds of thousands of new daily cases.

Queues of Covid-19 patients and their fearful relatives are building up outside hospitals in major cities across India, the new world pandemic hotspot which has now reported nearly one million new cases in three days, according to an AFP report.

Another 2,624 deaths, a new daily record, were reported in 24 hours, taking the official toll to nearly 190,000 since the pandemic started.

More than 340,000 new cases were also reported, taking India's total to 16.5 million, second only to the United States.
