After the Houthi armed group in Yemen launched attacks on government military camps and gatherings last week using one-way attack drones, it killed and injured dozens of government soldiers. But the internationally recognised Yemeni government was quick to retaliate by employing remotely operated drones to attack Houthi fighters on the front lines. That development is significant in Yemen's decadelong conflict because it highlights the growing use of drones on the battlefield. Government military units have repeatedly broadcast video footage showing drones tracking their targets, dropping bombs, killing fighters, destroying armoured vehicles and damaging hideouts. "The government side is now acquiring a potentially important tactical capability of its own," said Marius Bales, a doctoral researcher at the Bonn International Centre for Conflict Studies.

Is the war entering a new phase? Wildberries under fire: Why is Ukraine targeting a Russian retail giant? Many have compared Wildberries, Russia's largest online retailer, to Amazon, and some claim that, as in the case of the US company, shopping on its website or app feels addictive. "I know many people that are really addicted to it," Aleksandra, an accountant and mother in the Urals Mountains city of Yekaterinburg, Russia's fourth-largest, told Al Jazeera, withholding her last name for security purposes. "They add things to their basket, wait for discounts, make up their minds about what to buy, then decide to buy it again."

Is the war entering a new phase? 'New level of danger': Drone incidents scare Europe amid Russia-Ukraine war A quadcopter drone with plastic explosives attached to it flew unnoticed past air defence installations at Germany's Leipzig/Halle Airport, a key NATO airlift hub, on August 4. The drone hit a Ukrainian cargo plane but failed to detonate. It fell onto the tarmac and was found four hours later by a bus driver who stepped on it and called security, German media reported. DNA traces linked the drone to a firebomb that was mailed to the same airport and set a freight container on fire in July 2024, the Bild tabloid reported.

Has the army turned the page on control of western Sudan? In early August, Sudan's military and allied groups repelled two successive attacks by the RSF in the strategically important Bir Saliba region. It lies about 30km (nearly 20 miles) north of el-Geneina, the capital of West Darfur state and the RSF's last stronghold in the region. The strategy could signal a shift in fighting towards el-Geneina. Leading to el-Geneina, the Bir Saliba region is of strategic importance.

Is the war entering a new phase? 'Like the movies': How Ukraine's ground robots are changing rules of war A ground robot carrying ammunition and resembling a real-life cousin of Wall-E, the 2008 Pixar cartoon's rusty protagonist, got stuck late one night in a trench in northeastern Ukraine. Named Murakha (ant in Ukrainian), the robot was a bit more than a metre high, but had a large clearance to trudge across rugged terrain, bombed-out streets, mud, sleet or snow on tank-like tracks at up to 12km (7.5 miles) per hour. Sending a human rescue team to the front-line area was deemed too dangerous, an officer in charge of planning robotic missions said. Instead, the pilots managed to get another Murakha to pull the first one out with a rope.

What is Iran's Pickaxe Mountain? Where does Iran stand on Saudi-Pakistan-Turkiye pact? What are the challenges facing the Mecca agreement? Saudi Arabia and Pakistan have expanded their mutual defence pact to add Turkiye, raising questions about the emergence of a new security architecture at a time when the United States and Iran have yet to reach a final deal to end their war. Under the agreement signed in Mecca on Friday, any external armed attack on either of the three countries will now be considered an attack on all.

US researchers have announced the creation of new viruses using artificial intelligence, a scientific first that raises hopes for advances in medical treatments while also stoking anxiety about the dangers of the frontier technology. In findings published in the journal Science, researchers at Stanford University and the Broad Institute of MIT and Harvard said they used a naturally occurring phage - a type of virus that infects bacteria - as a template to generate thousands of genomes with AI. In tests, a mixture of the synthetic viruses proved more effective at killing E coli bacteria than the naturally occurring viruses, according to the findings. "Our approach expands what synthetic genomics can achieve alongside methods such as directed evolution and rational engineering, lays out a path for generating adaptive and resilient phage therapies against rapidly evolving pathogens, and establishes a foundation for the generative design of larger, more complex genomes," the researchers wrote in Science. Brian Hie and Samuel King, two of the paper's authors, did not immediately respond to requests for comment.

But he was acclaimed for his reforms while serving as Ukraine's minister of digital transformation, and his new duties included logistics, budgets, reforms, anticorruption measures and deals to secure multibillion-dollar Western aid or loans. After his appointment in January, Fedorov provided Ukrainian President Volodymyr Zelenskyy with a list of urgent problems and ways to solve them. He mentioned a "chaotic" management system, constant rotations of commanding officers, non-transparent distribution of arms and military equipment, bureaucracy, resistance to reforms from Commander-in-chief Oleksandr Syrskii's General Staff of Armed Forces, decision-making based on loyalty and not data analysis, and "isolation" of effective commanders and proponents of reforms. Then on Wednesday, just seven months into his role, Fedorov was removed from his position by Zelenskyy. The changes that Fedorov was trying to bring about in Ukraine's military had angered Syrskii. But Fedorov's ouster appears to have angered Ukrainians even more -- potentially presenting Zelenskyy with a political challenge. Rallies, relatively large by wartime Ukraine's standards, have since erupted in Kyiv and key Ukrainian cities. "He's a young, smart, educated person who proved with his previous job that he really is a reformer and can make Ukraine a nation of the future," Taisiya, who rallied on Thursday in central Kyiv, told Al Jazeera.

What is Iran's Pickaxe Mountain? The United States military says it has launched another wave of strikes on Iran, while Tehran says it retaliated with missile and drone attacks against US military assets in Kuwait, Bahrain and Jordan. US Central Command (CENTCOM), which oversees US military operations in the Middle East, said it concluded an evening wave of strikes against Iran at 9pm ET on Wednesday (01:00 GMT on Thursday), targeting "Iranian command centres, air defence sites, missile and drone capabilities, and coastal surveillance facilities" in an effort to reduce Iran's ability to disrupt shipping through the Strait of Hormuz. Iranian air defences were activated over the capital, Tehran, as state media reported attacks across much of the country. Explosions were reported in Bandar Abbas and on nearby Qeshm island in the south, as well as in the southeastern coastal towns of Sirik, Chabahar and Konarak. Iranian media also reported attacks further inland in Rask, Khondab, Khorramabad and Semnan.

It also alleges that Google "downloaded web scrapes of virtually the entire internet, including from known pirate sources and from behind legitimate paywalls". It further alleges that Google copied those works without permission to train its AI models and continues to do so, despite those uses allegedly falling outside the scope of existing agreements. The suit claims the company was fully aware of the legal risks, alleging that internal documents warned using books to train AI models was "highly problematic for Google," and could lead to as much as $100bn in fines. "At no point did Google inform authors and publishers that Google was copying their works as source material to develop and train AI models," the suit alleges. "It's an interesting issue that has a lot of complex dimensions, in no small part because it can be hard to prove what was or wasn't in a training corpus."
