Senior officers from countries across Europe and beyond will meet Thursday at a military headquarters on the outskirts of London to flesh out plans for an international peacekeeping force for Ukraine as details of a partial ceasefire are worked out.

U.K. Prime Minister Keir Starmer said the "coalition of the willing" plan, led by Britain and France, is moving into an "operational phase." But it's unclear how many countries are willing to send troops, or whether there will be any ceasefire to protect.

A French citizen imprisoned in Iran for over 880 days has been freed and is back home, as was another French citizen held under house arrest in Tehran, French officials said Thursday. Their liberation came as France and the rest of Europe are trying to jumpstart talks with Iran over its rapidly advancing nuclear program.

U.S. President Donald Trump has sent a letter to Iran's 85-year-old Supreme Leader Ayatollah Ali Khamenei seeking negotiations. Trump is also pressuring Tehran over its support of Yemen's Iran-backed Houthi rebels as the American military carries out an intense new campaign of airstrikes targeting the group.

Finland is named the happiest country in the world for the eighth year in a row, according to the World Happiness Report 2025 published Thursday.

Other Nordic countries are also once again at the top of the happiness rankings in the annual report published by the Wellbeing Research Center at the University of Oxford. Besides Finland, Denmark, Iceland and Sweden remain the top four and in the same order.

Israeli strikes killed at least 58 Palestinians across the Gaza Strip overnight and into Thursday, according to three hospitals. The strikes hit multiple homes in the middle of the night, killing men, women and children as they slept.

Hours later, the Israeli military restored a blockade on northern Gaza, including Gaza City, that it had maintained for most of the war. It warned residents against using the main highway to enter or leave the north and said only passage to the south would be allowed on the coastal road.

United Nations peacekeepers have observed seven Israeli activities in southern Lebanon violating U.N. Security Council Resolution 1701.

U.N. deputy spokesman Farhan Haq said the activities took place north of the U.N.-drawn boundary between Israel and Lebanon. The 2006 U.N. Security Council resolution requires Israeli forces to remain south of the boundary known as the Blue Line.

The Israeli military said it intercepted a missile launched from Yemen early Thursday before it reached Israeli airspace, as air raid sirens and exploding interceptors were heard in Jerusalem.

No injuries were reported. The Houthis said they fired a ballistic missile at Israel's international airport, the second such attack since the United States began a new campaign of airstrikes against the rebels earlier this week.

Early Thursday, a missile launched from Yemen was intercepted before reaching Israeli airspace, the Israeli military said.

Air raid sirens and several explosions were heard in Jerusalem, apparently the sounds of the interceptors in use. No injuries were reported. Yemen’s Houthi rebels did not immediately claim the attack Thursday morning.

Questions are mounting in Canada and in Europe over whether big-ticket purchases of high-end U.S. weaponry, such as the F-35 Joint Strike Fighter, are still a wise strategic choice for Western countries worried about their investment in U.S. defense technology.

In less than two months, U.S. President Donald Trump has upended decades of foreign policy. He has left NATO members questioning whether Washington will honor the trans-Atlantic alliance's commitment to defend each other, if other European countries are attacked by Russia. He's also made repeat overtures to Moscow and suspended most U.S. foreign aid.

Russia's illegal seizure of the Crimean Peninsula from Ukraine exactly 11 years ago on March 18, 2014, was quick and bloodless, but it sent Moscow's relations with the West into a downward spiral unseen since the Cold War.

It also paved the way for Russia's full-scale invasion of Ukraine in 2022, during which Moscow annexed more land from the war-torn country.
