The United States and Canada have wrangled for decades over trade, poking each other interminably over sore spots like Canadian softwood lumber imports and U.S. access to Canada's protected dairy market.

Somehow the two neighbors still managed to remain friends, allies — and trading partners. Canadian soldiers fought alongside Americans in Afghanistan after 9/11. The 5,525-mile U.S.-Canada border is undefended, and nearly 330,000 people and $2 billion dollars' worth of goods cross it every day; 800,000 Canadians live in the United States.

OpenAI is launching a version of ChatGPT designed for teenagers — the first generation to grow up with artificial intelligence — who are already using it for schoolwork, questions about daily life and even companionship.

The San Francisco-based company says ChatGPT for Teens, which launches Tuesday, is tailored for kids aged 13 to 17 with stronger protections including content restrictions around things like suicide, self-harm and romantic or sexual chats. It also provides homework and study support designed to help students learn rather than spit out answers and school essays.

The Palestinian American whose home in the occupied West Bank has been besieged for more than a week confronted Israeli settlers on his property Tuesday and demanded Israeli forces remove them from the area.

But on his first day back at his home in the village of Qusra, Loui Ridi was ultimately told to go inside because the area was a closed military zone.

Turkish President Recep Tayyip Erdogan has signed into law a measure that would introduce a conditional pardon for thousands of Kurdish militants as part of a government peace effort with the Kurdistan Workers' Party, or PKK.

The measure was published in the Official Gazette on Tuesday. It will only come into force after Turkey's National Security Council confirms that the group has fully dissolved itself and disarmed.

An unstable mountain rock formation looming above the Swiss village of Kandersteg threatens a landslide that could rival the disaster that destroyed nearby Blatten last year, a collapse scientists linked to thawing permafrost and glacier dynamics.

The 1,300 residents of Kandersteg, in Switzerland's Bern canton, live amid a quintessential Alpine landscape of sharp peaks, white glaciers, steep green valleys and the distant sound of cowbells.

Opening arguments are set to kick off Tuesday in a pivotal trial for Meta Platforms in a California federal court.

Attorneys general from California, Colorado, Kentucky and New Jersey are seeking extensive financial damages plus changes to how the company operates Facebook and Instagram. Twenty-nine states sued the tech giant in 2023 over child safety and privacy — the other 25 will go to trial later. The company also faces lawsuits in state courts.

Ukrainian forces staged one of their biggest drone attacks on Russia since Moscow's invasion more than four years ago, firing almost 800 drones just two days after launching a similar salvo, officials said Tuesday.

Meanwhile, a Russian missile strike on a village in Ukraine's northeastern Kharkiv region killed at least 10 people and wounded eight others as the barrage demolished homes, officials said Tuesday.

A hand grenade attack near a school in the Afghan capital Kabul on Monday afternoon wounded multiple children, authorities said.

Kabul police spokesman Khalid Zadran said late Monday that "a number of children" had been wounded, and said an investigation was underway. He did not provide further details.

Turkish President Recep Tayyip Erdogan has urged U.S. President Donald Trump in a telephone call to continue to seek a diplomatic solution to the conflict with Iran.

The call between the two presidents came late Monday as the 60-day negotiating period to find a peace deal between the United States and Iran was expiring, with no word of an extension and both sides seemingly as far apart as they were at the start.

A ship was hit by a projectile early Tuesday as it was sailing out of the Strait of Hormuz, according to the British military's UK Maritime Trade Operations center.

There was no immediate claim of responsibility but the attack highlights the ongoing danger of attempting to transit the waterway as Iran continues to throttle shipping traffic, even as it finalizes negotiations with Oman on a plan to manage the critical passage.
