A sea drone was used to save two crew members of a downed US army helicopter off the coast of Oman earlier this week, according to the US military - making it the first publicly known instance of an unmanned vessel being used to conduct a rescue mission. President Donald Trump said the apache helicopter was shot down by Iran near the Strait of Hormuz - the dangerous waterway which has been largely blocked off to shipping since the start of the Iran war. The two soldiers were safely rescued within approximately two hours and are in stable condition, US Central Command (Centcom) said. BBC Verify has examined what we know about the drone boat and how the mission took place. What is the US sea drone?

"Defenders cannot afford to take weeks to patch," one Cybersecurity and Infrastructure Security Agency official warned on Wednesday. With new generations of AI models fueling both rapid software vulnerability discovery and the potential for faster exploitation by malicious hackers, the United States Cybersecurity and Infrastructure Security Agency released a new directive on Wednesday that requires more rapid and efficient software patching by federal civilian agencies. The "binding operational directive" (BOD) lays out a rubric for how quickly bugs must be fixed based on four assessments of urgency, with a turnaround time in critical cases of just three days. Chris Butera, CISA's acting executive assistant director for cybersecurity, told reporters on Wednesday that the goal of the directive is to help agencies prioritize, so they can address the most problematic vulnerabilities first while taking more time to remediate bugs that pose a less-pressing risk. The directive comes as private companies and governments have been scrambling to assess the extent of the cybersecurity reckoning that AI vulnerability and exploit development capabilities could unleash.

Trump Risks Key Surveillance Authority Over'Unqualified' Spy-Chief Pick US lawmakers are alarmed that Bill Pulte, a housing official with no intelligence experience, is poised to take charge of one of the government's most powerful surveillance tools. A sweeping warrantless surveillance authority remains on track to expire Friday, with no clear path to a deal, after President Donald Trump refused this week to abandon his pick of housing official Bill Pulte to temporarily lead the US intelligence community--even tasking Pulte with gutting the Office of the Director of National Intelligence in a DOGE-style "downsizing" before a permanent director is named. In a Truth Social post after his second White House meeting in two days with House speaker Mike Johnson, Trump called Section 702 of the Foreign Intelligence Surveillance Act "very important to our military, and keeping the American people safe" and asked Congress for a short-term extension to give him time to find a permanent director of national intelligence. Section 702 lets the government collect the communications of foreign targets abroad without a warrant, sweeping in an unknown volume of Americans' messages that the FBI can later search. It faces a first-ever lapse in its legal authorization if Congress does not act by the end of Friday, June 12.

Fully autonomous drones with no human oversight have killed soldiers on the battlefield for the first time. This is according to a senior figure in the Ukrainian defence industry, marking a watershed moment in warfare. The one-off test involved 10 AI-controlled "Terminator" drones on the front line of the Ukraine war. "We tried it," says drone-maker Alexander Kokhanovskyy, who supplied the technology and spoke to at a press event hosted by the Ukrainian embassy. We never implemented it [more widely]." The test took place two years ago and involved quadcopter drones that were programmed to fly towards the front line, cover between 3 and 5 kilometres over around 10 minutes and then engage "Terminator mode", in which an AI model searches for and intercepts targets. "We just launch it and we know everything will be dead - everything that will be found there in this particular area will be dead," says Kokhanovskyy. "There is no connection to the drone at all, you cannot see the video, ...

Ukrainian forces have carried out a missile attack deep inside Russia, hitting a major military plant overnight, President Volodymyr Zelensky has said. He said FP-5 Flamingo cruise missiles struck the drone and missile plant in the city of Cheboksary, in the Chuvash Republic, more than 900km (560 miles) from the front line. Local officials said three people were injured in a missile attack on the city. Ukraine also said it had hit the Moscow-occupied port of Mariupol on the Sea of Azov, a Russian oil refinery in Samara and a shadow fleet oil tanker in the Black Sea. In recent months, Ukraine's military has intensified its drone strikes on key facilities across Russia.

Recent incidents heighten anxieties that hybrid warfare tactics could trigger military confrontation with Russia. Lithuanian armed special forces and members of the Lithuanian Riflemen's Union take part in a military exercise in central Lithuania [File: Nils Adler/Al Jazeera] A member of the Lithuanian Riflemen's Union joins in military exercises in central Lithuania [File: Nils Adler/Al Jazeera] Along the forests and marshlands that separate the Baltic states from Russia and Belarus, workers are digging anti-tank ditches, pouring concrete bunkers and erecting rows of dragon's teeth - jagged concrete obstacles designed to slow and channel advancing armour - to buy precious time in the event of an attack. Russia's full-scale invasion of Ukraine in 2022 reignited old fears in Estonia, Latvia and Lithuania, where memories of Soviet rule remain close to the surface. In the years since, those fears have been channelled into preparation. Defence budgets have surged, military exercises have intensified, and new fortifications have emerged even as daily life largely continues as normal.

Ukrainian drones have struck a historic museum in Russia-annexed Sevastopol in Crimea, igniting a roof fire, as Russian authorities slashed nighttime train schedules amid intensifying air attacks across the peninsula and deep into Russia. Sevastopol's Russian-installed governor, Mikhail Razvozhayev, announced the damage on Telegram early on Wednesday. "This building is not just a museum, it is a symbol of resilience, which has repeatedly taken the blows of the enemy." Razvozhayev said that during World War II's Siege of Sevastopol, "the Panorama building was subjected to massed bombing by German aviation". He declared: "The enemy will pay for this sacrilege!"

Uncrewed ground vehicles have already been tested for defending the front line by the Ukrainian military. There's a received piece of wisdom among militaries around the world that whatever new technologies appear, in the end, foot soldiers are what matters. As British Army officer Field Marshal Archibald Wavell put it shortly after the second world war: "All battles and all wars are won in the end by the infantryman." This may now finally be changing. Robots in battle are about to reach a critical point for Ukraine. In May, it began the mass production of Legit, a low-cost robot capable of carrying a machine gun.

In the five years since Myanmar's military chief led a coup to overthrow the democratically elected government, civil war has torn the country apart. Thousands have been killed and millions displaced by the conflict between the military and an alliance of ethnic and rebel groups. More than two years ago, the rebels made a series of sweeping gains, but things have taken a turn for the worse for them. Forced conscription and increased drone power has put the military on the offensive in most parts of the country. The BBC's Quentin Sommerville travelled to Myanmar without the permission of the authorities - the only way to report from rebel-held territory.
