Global markets were mostly lower and Japan's stock index tumbled Thursday as the U.S. dollar sank against the yen after the head of the Federal Reserve suggested a cut to interest rates will come soon.

France's CAC 40 slid 1.3% in early trading to 7,433.71. Germany's DAX declined 1.3% to 18,275.40, while Britain's FTSE 100 fell 0.3% to 8,347.45. The future for the S&P 500 edged 0.1% higher while that for the Dow industrials fell 0.1%.

With large parts of the world in turmoil and deep uncertainty over the future direction of America's global role, U.S. Secretary of State Antony Blinken sought this week to project an aura of calm normalcy as he traveled through Asia on his first overseas mission since President Joe Biden jolted the 2024 presidential race with his withdrawal.

Whether he succeeded or not remains an open question.

South Korea on Thursday offered to send aid supplies to North Korea to help the country recover from heavy rains and floods that submerged thousands of homes and huge swaths of farmland.

It's unclear whether North Korea would accept South Korea's proposal for help. Animosity between the war-divided rivals is at its highest in years over the North's growing nuclear ambitions and the South's expansion of combined military exercises with the United States and Japan to counter the North's threats.

Prime Minister Keir Starmer summoned British police chiefs for a crisis meeting on Thursday over violent unrest that followed a stabbing attack that left three young girls dead. A 17-year-old suspect appeared in court to face three counts of murder and 10 of attempted murder.

The attack on children at a Taylor Swift-themed summer holiday dance class shocked a country where knife crime is a long-standing and vexing problem. The deaths have also been used by far-right activists to stoke anger at immigrants and Muslims – though the suspect is not an immigrant, and his religion has not been disclosed.

Moldova's Ministry of Foreign Affairs said Thursday it has expelled a Russian diplomat after two Moldovan officials were detained on suspicion of treason and conspiracy against the European Union candidate country.

One of the Moldovan officials is suspected of treason for allegedly collecting and providing information to an embassy employee that could be used against Moldova's interests, the Prosecutor's Office for Combating Organized Crime and Special Cases said, and the other is accused of plotting against the country for personal gain.

Ismail Haniyeh was the international face of Hamas, its top leader in exile who kept up the militant group's ties with allies around the region. At the head of its political hierarchy, he had little military role – but Israel marked him for death after the surprise Oct. 7 attacks.

The 62-year-old Haniyeh was killed in an airstrike Wednesday during a visit to one of Hamas' most crucial allies, Iran, after attending the inauguration of its new president. Iran and Hamas both accused Israel, which has not commented on the strike.

A pair of assassinations of anti-Israel militant leaders hours apart is threatening to set off a regional clash and upend already fragile talks aimed at ending the war in Gaza.

The deadly round of strikes, retaliation and negotiations escalated Wednesday when Hamas' political chief, Ismail Haniyeh, was killed, hours after he attended the inauguration of Iran's new president in Tehran. Israel has not claimed responsibility, but Iran threatened revenge against Israel.

Two Al-Jazeera reporters were killed in an Israeli strike in northern Gaza on Wednesday, the satellite news network said, the latest Palestinian journalists working with the Qatari network to be killed in the war-torn enclave.

Correspondent Ismail al-Ghoul, 27, cameraman Rami al-Rifi and a child who was not identified were killed in a blast that struck a car in Gaza City that the three were traveling in, according to the network and the Emergency and Ambulance Service, which helps recover and transport casualties to hospitals across Gaza.

The Israeli military said Thursday that it has confirmed that the head of Hamas' military wing, Mohammed Deif, was killed in an airstrike in Gaza in July.

Israel targeted Deif in a July 13 strike that hit a compound on the outskirts of the southern Gaza city of Khan Younis, but the military said for weeks it was working to determine if he died in the blast. Hamas has denied he was killed. More than 90 other people, including displaced civilians in nearby tents, were killed in the strike, Gaza health officials said at the time.

Israel's suspected killing of Hamas' political leader in the heart of Tehran, coming after a week in which Prime Minister Benjamin Netanyahu promised U.S. lawmakers he would continue his war against Hamas until "total victory," points to an Israeli leader ever more openly at odds with Biden administration efforts to calm the region through diplomacy.

U.S. Secretary of State Antony Blinken, speaking on an Asia trip, was left to tell reporters there that Americans had not been aware of or involved in the attack on Hamas political leader Ismail Haniyeh, whose roles included overseeing Hamas' side in U.S.-led mediation to bring a cease-fire and release of hostages in the Gaza war.
