Global shares mostly declined on Tuesday as recent enthusiasm cooled and markets faced uncertainty about efforts to end the war in Iran.

France's CAC 40 dipped 1.0% in early trading to 8,313.86, while the German DAX fell 1.6% to 24,746.63. Britain's FTSE 100 declined 0.6% to 10,379.26. U.S. shares were set to drift lower with Dow futures down 0.7% at 51,774.00. S&P 500 futures fell 1.5% to 7,429.25.

Lionel Messi, Kylian Mbappé and Erling Haaland have taken their expected starring roles so far in the World Cup.

Cristiano Ronaldo is getting some unexpected criticism.

German Chancellor Friedrich Merz pledged Tuesday to push through a proposed reform of the country's creaking pension system that would include raising the retirement age gradually in line with life expectancy, declaring that "failure is not an option."

Merz's coalition of center-right and center-left parties took office just over a year ago with pledges to reform and turn around Germany's sluggish economy, Europe's biggest. It has since become deeply unpopular, in part because of perceptions that it has squabbled but so far achieved little.

Iran's president was traveling to Pakistan on Tuesday for talks with officials who have been mediating negotiations between Tehran and Washington on a permanent end to the war in the Middle East.

President Masoud Pezeshkian's visit to Islamabad comes as technical teams are working on details of the deal, following high-level negotiations in Switzerland on Monday led by US Vice President JD Vance and Iran's parliamentary speaker, Mohammad Bagher Qalibaf.

Security forces in the Turkish capital carried out sweeping raids on Tuesday ahead of next month's NATO summit, and detained more than 200 people with suspected links to extremist groups, including the Islamic State group.

U.S. President Donald Trump is expected to join other leaders of the 32‑member alliance in Ankara for the July 7–8 summit.

Ship traffic has picked up in the Strait of Hormuz since Iran and the U.S. signed an interim deal to end a war that constricted global oil supplies and fueled inflation, but questions surrounding control of the vital waterway and whether vessels will be charged tolls to cross it could interfere with negotiations to forge a lasting peace.

Tehran and Washington clashed over the Strait of Hormuz again this past weekend. Citing Israel's latest attacks on Lebanon, Iran declared that it reclosed the strait. The U.S. was quick to contest that. Maritime tracking data showed that dozens of ships passed through on Saturday and Sunday, though far fewer than the daily average before the war.

U.S. Secretary of State Marco Rubio will travel to the United Arab Emirates, Kuwait and Bahrain this week as the Trump administration has stepped up efforts to end the war with Iran while Gulf countries remain uneasy about a proposed deal.

The State Department announced Monday that Rubio would visit the three countries for bilateral meetings with leaders to discuss the memorandum of understanding reached last week between the U.S. and Iran, weekend talks in Switzerland between senior Iranian and U.S. officials as well as security for American allies and partners in the Middle East, including the status of the Strait of Hormuz.

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.
