India has recorded the highest one-day tally of new Covid-19 cases anywhere in the world - and the country's highest number of deaths over 24 hours.

It has close to 16 million confirmed cases, second only to the US.
The country is struggling with a second wave, raising more fears about its overwhelmed health care system.
Crowds have formed outside hospitals in major cities which are filled to capacity. A number of people have died while waiting for oxygen.
Families are waiting hours to perform funeral rites, Reuters news agency reports, with at least one Delhi crematorium resorting to building pyres in its car park in order to cope with the numbers arriving.
Meanwhile, some countries are bringing in stricter rules affecting travel to and from India amid fears over the rising cases.
Australia's Prime Minister Scott Morrison said the number of flights between the two countries would be cut, while the UK has added India to a red list, restricting travel and bringing in hotel quarantine for all arrivals from India from Friday morning.
What's happening in India's hospitals?
India is struggling to cope with the soaring numbers - it recorded some 314,835 new coronavirus cases in the past 24 hours, while deaths rose by 2104.
Oxygen supply has been a particular problem, with a number of hospitals in the capital Delhi running out entirely on Thursday, according to the city's Deputy Chief Minister, Manish Sisodia.
Numerous other hospitals are understood to be running dangerously low on supplies, including one treating another Indian politician, Saurabh Bharadwaj.
Delhi legislature member Bharadwaj posted a plea for help in Hindi on Twitter from his hospital bed, saying there were just three hours of oxygen left.
"A lot of people are dependent on oxygen and without oxygen, these people will die just like fish die in the absence of water," he said, according to a translation by news channel NDTV. "This is a time for all to come together to work."
The crisis worked its way to Delhi's highest court on Wednesday, where judges publicly criticised the central government for its handling of the oxygen crisis in the city.
"This is ridiculous. We want to know what the centre is doing with regard to oxygen supply across India," the judges said while reading out the verdict in a petition by the owner of six private hospitals.
On Thursday, as hospitals warned stocks were rapidly diminishing, Prime Minister Narendra Modi held a meeting to attempt to end the crisis. He asked officials to find ways to produce more oxygen, while telling states to come down "heavily" on anyone hoarding supplies.
How is India trying to contain cases?
Unlike last year, no national lockdown has been announced. Instead, regions are implementing their own rules.
Delhi announced a week-long lockdown at the weekend, leaving just government offices and essential services like hospitals, pharmacies and grocers open.
The authorities in the worst affected state of Maharashtra - which was already under a partial lockdown - have announced a series of additional restrictions starting from Thursday evening.
Maharashtra is India's richest state and home to its financial hub, Mumbai. It has also been a Covid-19 hotspot since the start of the pandemic, accounting for a quarter of India's cases.
Maharashtra has also reported more deaths from the virus than any other state, with 67,468. India has suffered nearly 185,000 deaths with Covid-19, according to Johns Hopkins University. However, while deaths have been rising, the fatality rate remains relatively low.
Uttar Pradesh, which is also reporting a high caseload, has adopted a more conservative approach, with its high court on Monday ordering a lockdown in five badly affected districts. However, it was put on hold after the government appealed against the decision in the Supreme Court.
How is India's vaccination drive going?
India - which has a population of more than a billion people - has so far administered more than 130 million doses but the drive has been restricted to health workers, frontline staff, those above the age of 45 and anyone with co-morbidities.
From 1 May, people above 18 will also be eligible for the vaccine. But a supply crunch, which is already affecting the drive, could slow it down further.
The crunch has impacted the Covax programme, which was heavily dependent in India's Serum Institute. It told the BBC it had suffered a shortfall of around 90 million doses after India prioritised its own needs, but says talks are now taking place to resume production.
Pharmaceutical company Pfizer announced it was in ongoing discussions with the Indian government to supply its Covid-19 vaccine to the country at a not-for-profit price, according to Reuters news agency.
What caused the latest wave?
India has seen a rapid rise in case numbers over the past month driven by lax safety protocols, a Hindu festival attended by millions and variants of the virus, including a "double mutant" strain. It was detected in 61 percent of samples tested in Maharashtra, according to the National Institute of Virology.
Huge election rallies - including by Prime Minister Narendra Modi - were also not halted in the state of West Bengal which has been holding elections in phases in recent weeks. The government has defended the decision to continue with the polling.
