Millions of people across France woke up drenched in sweat on Tuesday after another night of scorching heat, with most of the population exposed to extreme and exceptional temperatures.

Temperatures will remain exceptionally high around the clock as the national weather service, Meteo France, placed 54 departments under a red heat wave alert.

Mexico, Kenya, Italy and other nations around the world are experiencing one to two more months of heat stress than they were several decades ago, new research published Monday says, and some areas even more so. Regions previously untouched by heat stress are now feeling it, too.

Extreme feels-like temperatures, heat stress days and tropical nights have all become dramatically more frequent, long and severe over the past six decades as the planet's warming intensifies — a result of the burning of fossil fuels coal, oil and gas — according to a new study published in the journal Nature Climate Change on Monday.

Lionel Messi set a World Cup record with his 17th and 18th goals, and defending champion Argentina advanced to the knockout stage with a 2-0 victory over Austria on Monday.

Messi had a golden opportunity to break the record in the ninth minute, but went wide to the right on a penalty kick. Almost 30 minutes later, Messi caught Alexander Schlager leaning the wrong way after Thiago Almada let Facuno Medina's pass go by him directly onto Messi's left foot.

After a first round of U.S.-Iran talks in Switzerland on ending the Middle East war, mediators Pakistan and Qatar said on Monday that Tehran and Washington had agreed to set up a "de-confliction cell" with Lebanon "to ensure the adherence of the termination of military operations" there.

Under U.S. pressure, Lebanese officials began direct talks with Israel in April in Washington, and a fifth round of negotiations is scheduled to begin on Tuesday.

Trading is mixed early Monday and oil prices edged lower on fresh optimism over progress in U.S.-Iran negotiations.

Futures for the S&P 500 inched back 0.1% before the opening bell, while futures for the Dow Jones Industrial Average were unchanged. Nasdaq futures ticked up 0.1%.

British Prime Minister Keir Starmer announced his resignation on Monday after fewer than two years in office in a term characterized by policy U-turns and deep public unpopularity.

"Every decision I have taken has been about putting the country I love first. That is why I will resign as leader of the Labour Party," Starmer said as he choked up in an emotional speech outside 10 Downing Street.

It's a very starry Monday for the World Cup.

Iran took another step toward advancing in the World Cup on Sunday, but once again the off-the-field play dominated the conversation.

At the match's conclusion, at least one attendee wearing a pre-revolutionary flag shirt was detained for trying to run onto the pitch. And afterward, though demonstrations were quieter than Monday's, an Associated Press reporter observed a fan who got into a scuffle with protesters being loaded into an ambulance.

Egypt's players danced on the field while their red-clad fans celebrated in the stands. The Pharaohs finally got their first World Cup win.

Mohamed Salah scored the go-ahead goal and Egypt went on to defeat New Zealand 3-1 on Sunday night.

France gritted its teeth Monday for a week of record-busting temperatures, sweltering under a grueling heat wave that combines daytime highs above 40 degrees Celsius (104 Fahrenheit) and sleep-robbing sweaty nights.

The national weather service, Meteo France, said that most of the country — the largest in the European Union and second most populated — is entering what is described as a "plateau" of unrelenting heat-wave conditions that isn't forecast to start easing before Friday at the earliest.
