Sudan's army has denied it carried out a deadly attack on a major hospital on Friday night in a city in the west of the country held by its rivals, the paramilitary Rapid Support Forces (RSF). The head of the World Health Organization (WHO) said 64 people - including 13 children, two nurses and a doctor - had died in the strike on el-Daein Teaching Hospital and 89 others had been wounded. Enough blood has been spilled, Tedros Adhanom Ghebreyesus posted on X, urging the warring parties to end the conflict, which started nearly three years ago. The RSF said an army drone had hit the hospital in el-Daein, the capital of East Darfur state, on the day Muslims were marking the festival of Eid. Sudan was plunged into a civil war in April 2023 when a vicious struggle for power broke out between the military and the RSF, who had once been allies after coming to power in a coup in 2021.

Readers respond to Burkhard Bilger's piece about turbulence, Gideon Lewis-Kraus's article on Anthropic, Ava Kofman's story concerning surrogacy, and Katy Waldman's essay about fawning. Burkhard Bilger's recent story about aviation turbulence opens with a dramatic account of a Singapore Airlines flight, SQ321, in May, 2024 (" Buckle Up," March 9th). The plane hit clear-air turbulence over Myanmar's Irrawaddy River, causing it to drop almost two hundred feet in an instant. During the Second World War, U.S. Army Air Forces transport planes confronted the same weather system. Flying from northeast India, over "the Hump" of intervening mountain ranges, to southwestern China, pilots routinely encountered turbulence that dropped and lifted their aircraft not hundreds of feet but thousands.

'We will go wherever they hide': Rooting out IS in Somalia A figure appears in the picture, moving through a valley. He has been to fetch water for his friends, says the drone operator. He is running and carrying something on his back, adds another soldier. The man on the screen is near a cave, which the army believes is a hideout for 50 to 60 IS fighters. The Puntland Defence Forces have about 500 soldiers stationed at this base in the north-east of Somalia. Ten years ago the barren and inhospitable landscape was home to only a few nomadic communities, but that changed when IS established a foothold here, shifting its focus to Africa as its fighters were driven out of their strongholds in Syria and Iraq.

As Iranian-designed Shahed drones spread from Ukraine to the Gulf, U.S. and allied forces are using multimillion-dollar air defenses to counter low-cost attacks, raising sustainability concerns.

In modern warfare, we must defeat Russia in every technological cycle, the country's defense minister said. Ukraine's four-year war with Russia has made it the world leader in battlefield drone technology. One byproduct of that is that the data it collects has become one of the country's most valuable assets. On Thursday, Ukraine played that card, saying it will begin sharing its battlefield data with allies to train drone AI software. In modern warfare, we must defeat Russia in every technological cycle, Ukraine Defense Minister Mykhailo Fedorov wrote on Telegram (translated from Ukrainian).

Why the world's militaries are scrambling to create their own Starlink The reliable internet connections provided by Starlink offer a huge advantage on the battlefield. Starlink's satellite constellation provides a reliable internet connection to almost anywhere on Earth, conferring an advantage on the modern battlefield. But it is also run by controversial billionaire Elon Musk, presenting a risk to militaries that could easily find themselves cut off. So, now countries are racing to build their own version. The Starlink network consists of almost 10,000 satellites that offer internet connections across most of the planet via small dishes on the ground.

Drones aren't yet licensed to carry passengers, but some may already be airlifting wounded personnel off the battlefield and could be employed for smuggling people Still from a promotional video for Skysurfer, a US company that sells "ultralight aircraft" for personal, recreational use The first passenger-carrying drones may already be in use. These aren't sophisticated urban air taxis, but crudely modified cargo drones transporting combat casualties and criminals. Heavy-lift drones are essentially scaled-up versions of the familiar quadcopters. Hair-raising videos of hobbyists carried by home-made drones show that the basic technology is simple enough. But meeting aircraft safety requirements for passenger transport takes years, and drone-makers, including Volocopter, EHang and Eve Air Mobility, are all aiming to get vehicles certified this year or next.

Ukraine has responded to a war it didn't start by creating an industry it doesn't want, but could the nation's drone expertise help it rebuild? To learn more, gained exclusive access to the research labs, factories and military training schools behind Ukraine's drones Killhouse Academy, run by the 3rd Assault Brigade, is Ukraine's leading drone-pilot school. The grinding, attritional war between Russia and Ukraine is now entirely dominated by drones. Russia pummels Ukraine with long-range kamikaze aircraft and Ukraine knocks them out of the sky with specialised interceptors. The front line has transitioned from an artillery battle to a first-person-view drone fight, while ground-based robots are increasingly used to deliver ammunition and supplies, launch attacks and evacuate the wounded. As a result, in the four years since Russia's full-scale invasion, Ukraine has created from nothing an entire industry and ecosystem capable of designing, manufacturing and operating a variety of ingenious drones.

Samsung Galaxy Unpacked 2026 is Feb. 25 Russia's recent blocking of Telegram is reportedly disrupting its military operations in Ukraine Telegram is among a number of Western apps banned by Russian authorities. A decision to ban Telegram on home soil may have backfired on the Kremlin. Last week, Russia went on a, banning a number of Western apps in an effort to push domestic users towards Max, an unencrypted state-owned app. One of the restricted apps was WhatsApp (which was also blocked) rival Telegram, a move that drew rare internal from soldiers and pro-war bloggers, with the army being heavily reliant on the cloud-based messaging service for communications. As reported by, pro-Russian military channels are now complaining that the sudden Telegram blackout -- coupled with Elon Musk Russia's access to Starlink earlier this month -- is now actively harming frontline operations.

Are drones, AI making it harder to fight armed groups in the Sahel? The brazen attack on the international airport and nearby military airbase in Niamey, Niger's capital, came overnight between January 28 and 29. Balls of orange fire flew across the sky as the Nigerien army attempted to respond while residents ducked for cover and whispered prayers, as shown in videos on social media. ISIL (ISIS) in Sahel Province, or ISSP - a Niger-based outfit earlier known as the ISIL affiliate in the Greater Sahara or ISGS - has since claimed responsibility and says it killed several soldiers, although the Nigerien army disputes this. Many of its fighters had breached military drone hangars using RPGs and mortars, and managed to damage several aircraft and one civilian aeroplane, according to videos from the group.
