COVID-19 deaths worldwide have surpassed the grim milestone of four million.
It took more than a year for the global death toll to hit two million, but less than 170 days for another two million to be recorded.
The U.S. remains as the country with the highest number of fatalities, followed by Brazil and India.
However, India and Brazil, have reported the most deaths each day over the last 24 hours.
The three countries together account for about 40 percent of the world's coronavirus-related deaths.
Health officials, including the World Health Organization, expect the world death toll to be much higher than the current figure believing that many deaths may not have been accounted for in countries with overwhelmed medical systems.
In the UK, more than 11-thousand new COVID-19 cases were reported on Thursday, along with 19 deaths.
A study shows that infection rates have been increasing across all age groups, but particularly higher among those in their twenties.
Health experts say the current wave of infections is driven by the highly transmissible Delta variant, and warned that cases may peak in the coming days.
In Japan where many are concerned about the upcoming Olympic Games the country is seeing a decline in daily figures.
But the host city of the Summer Olympics, Tokyo, is seeing a resurgence, reporting 452 cases on Thursday.
The Japanese government, however, has decided to lift its state of emergency this Sunday in nine metropolitan regions, including the capital, citing the recent decline in new cases.
Russia, which is hosting six Euro 2020 games, is also facing a sharp increase in the number of new COVID-19 infections.
Moscow is now seeing infection numbers as high as December last year and doctors across Russia have seen a 30 percent increase in cases last week amid significant spread of the Delta variant.
