Cyclone Tauktae has killed at least 12 people and left a trail of destruction as it brushed past the coastal states of Kerala, Karnataka, Goa and Maharashtra, authorities said.

It is set to make landfall in Gujarat late on Monday.

"This will be the most severe cyclone to hit Gujarat in at least 20 years. This can be compared with the 1998 cyclone that hit Kandla and inflicted heavy damage," state revenue secretary Pankaj Kumar told Reuters.

The cyclone increases pressure on local administrations already struggling with a high caseload of Covid-19 infections.

The government said 80 people arrived in Darwin on Saturday, and would be quarantined for a fortnight.

Their Qantas flight was originally scheduled to carry 150 people onboard.

But 70 passengers were later barred from travel after testing positive for coronavirus or coming into close contact with others who were.

Australia's strict rules on pre-flight testing meant there was not enough time for the seats to be given to others waiting to return.

Deaths from Covid-19 swelled by 4205, while daily coronavirus cases rose by 348,421, with India's overall number of cases surging past 23 million, according to health ministry data.

Even then, experts believe the official numbers grossly underestimate the real scale of the epidemic's impact, and actual deaths and infections could be five to ten times higher.

India's Covid-19 infection curve may be showing early signs of flattening, but the decline in the number of new infections is likely to be slow, top Indian virologist Shahid Jameel said.

The Indian government has told medics to look out for signs of mucormycosis in coronavirus patients following an increase in cases of the rare but potentially fatal infection.

The disease can lead to blackening or discolouration over the nose, blurred or double vision, chest pain, breathing difficulties and coughing blood.

It is strongly linked to diabetes, which can in turn be exacerbated by steroids, such as dexamethasone, used to treat severe COVID-19.

The discovery, near the border between the states of Bihar and Uttar Pradesh, was confirmed to the BBC on Monday.

It is not clear how the bodies came to be there, but local media reports suggest they may be Covid-19 victims.

Some media reports say as many as 100 bodies have been found, and that their condition suggests they may have been in the river for several days.

"There is a possibility that these bodies have come out of Uttar Pradesh," a local official, Ashok Kumar, told the BBC after questioning local residents.

The government's controversial ban, which made it an offence for people to try and re-enter Australia after being in India within the prior 14 days, began on Monday and was due to finish on 15 May.

Morrison said the National Security Committee met yesterday and agreed it saw "no need to extend it beyond that date".

"The original decision to put in place that biosecurity order until the 15th of May has proved very effective and it will run its full course until that time without any change," he said.

The prime minister is resisting the move due to the economic impact.

India added more than 355,000 cases on Tuesday, down from more than 400,000 daily infections on 30 April.

The government says cases are "slowing down", but testing numbers have also dipped, meaning the true caseload could be far higher.

Confirmed infection numbers have however been consistently falling in Maharashtra state, which has driven the second wave since early April.

Hospitals in the city are in crisis, with intensive care beds full and an acute shortage of medical oxygen.

Delhi's government wants the army to run Covid care facilities and intensive care units.

Across India, case numbers since the start of the outbreak are closing in on 20 million.

The country has seen more than 300,000 new cases a day for nearly two weeks straight while deaths stand at 220,000.

Experts say total Covid cases and deaths in India are likely to be much higher, citing lack of testing and patients dying at home without being seen by doctors.

The health ministry said the ruling had been made "based on the proportion of people in quarantine who have acquired a Covid-19 infection in India".

Earlier this week, Australia banned all flights from India.

There are an estimated 9,000 Australians in India, 600 of whom are classed as vulnerable.

This will be the first time Australians have been criminalised for returning to their country, Australian media report.

One doctor told ABC that the government's move was disproportionate to the threat posed by those returning from India.

Its health ministry said 3,689 people had died within the past 24 hours.

Prime Minister Narendra Modi met the health minister on Sunday morning to review the crisis.

Hospitals are battling to treat patients amid a chronic shortage of beds and medical oxygen.

Amid the crisis, vote counting started on Sunday for elections held in four states: Assam, West Bengal, Tamil Nadu, and Kerala - and the union territory of Puducherry.
