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.

An explosion tore through Qatar's key natural gas export terminal Sunday night as workers tried to resume operations there after Iran bombed it during the war, causing a fire that hurt at least 54 people as another 18 were still missing hours later.

The blast at the Ras Laffan industrial area could cause further chaos in global energy markets, particularly as Qatar remains one of the world's top natural gas producers. Qatar shut down its production after Iran's chokehold on the Strait of Hormuz meant it couldn't get shipments out to its clients.

The dust has barely settled in Tyre after weeks of Israeli airstrikes on the ancient city along Lebanon's Mediterranean coast.

Despite the relative calm, life remains largely at a standstill.

Mourners gathered Sunday in Beirut to pay their respects to a much-loved Lebanese conservationist who died after succumbing to wounds sustained in an Israeli strike on her home on the country's southern coast.

Mona Khalil, who spent more than two decades protecting sea turtles along Lebanon's coastline, was critically injured in the strike on her home in the village of Mansouri earlier this month and died of her wounds Friday. She was 76.

Israeli President Isaac Herzog told Fox News that a peace agreement between Israel and Lebanon cannot be reached if Iran is “trying to squeeze themselves into this conflict” via the Iranian-backed Hezbollah militant group.
