Former U.S. ambassador to Ukraine John Herbst explains the impact of the drone strike on Russian air bases. Russian and Ukrainian delegations have begun talks in Istanbul, Turkey, on Monday, less than 24 hours after a massive Ukrainian drone attack struck Russian airfields. The two delegations entered Ciragan Palace in Istanbul alongside a group of senior Turkish officials. It is the second round of peace talks to take place in the three years since Russia invaded Ukraine. Images from the event show many of the Ukrainian delegation wearing military uniforms, while the Russian group exclusively wore suits.

Kyiv, Ukraine – Any description of Ukraine's attacks on Russia's fleet of strategic bombers could leave one scrambling for superlatives. Forty-one planes – including supersonic Tu-22M long-range bombers, Tu-95 flying fortresses and A-50 early warning warplanes – were hit and damaged on Sunday on four airfields, including ones in the Arctic and Siberia, Ukrainian authorities and intelligence said. Moscow did not comment on the damage to the planes but confirmed that the airfields were hit by "Ukrainian terrorist attacks". Videos posted by the Ukrainian Security Service (SBU), which planned and carried out the operation, which was called The Spiderweb, showed only a handful of planes being hit. The strategic bombers have been used to launch ballistic and cruise missiles from Russian airspace to hit targets across Ukraine, causing wide scale damage and casualties.

Fox News senior White House correspondent Peter Doocy questions President Donald Trump about the Russia-Ukraine war. The brazen Ukrainian blitz of Russian warplanes Sunday was 18 months in the making and the Pentagon was kept in the dark until it was over, sources told Fox News. "Operation Spider's Web," a series of coordinated drone strikes penetrating deep into Russian territory, is believed to have taken out dozens of Russia's most powerful bomber jets and surveillance planes as they sat idle on five military airfields. The stunning operation was personally overseen by President Volodymyr Zelensky, Ukraine's security service (SBU) said. Ukraine used small FPV drones hidden inside wooden cabins mounted on trucks.

Ukrainian forces destroyed dozens of Russian warplanes with a drone attack on air bases deep within Russian territory on Sunday. Ukrainian forces destroyed 40 aircraft in the attack, which an official says took more than a year to orchestrate. Russia's defense ministry confirmed the attack on Sunday, saying it struck five airfields. The operation saw drones transported in containers carried by trucks deep into Russian territory, he said. The drones reportedly hit 41 planes stationed at several airfields on Sunday afternoon, including A-50, Tu-95 and Tu-22M aircraft, the official said.

Officials say multiple military airbases have come under drone attacks in Russia in a major operation taking place ahead of peace talks with Ukraine due to start in Istanbul on Monday. The Russian Defence Ministry said that Ukraine had launched drone strikes targeting Russian military airfields across five regions on Sunday, causing several aircraft to catch fire. The attacks occurred in the Murmansk, Irkutsk, Ivanovo, Ryazan, and Amur regions. Air defences repelled the assaults in all but two regions – Murmansk and Irkutsk, the ministry said. "In the Murmansk and Irkutsk regions, the launch of FPV drones from an area in close proximity to airfields resulted in several aircraft catching fire," the ministry said.

Russian drone and missile attacks on Ukraine have killed at least two people, according to officials, as Ukraine ordered the evacuation of 11 more villages in its Sumy region bordering Russia. Russian troops launched an estimated 109 drones and five missiles across Ukraine on Friday and overnight, the Ukrainian air force said on Saturday, adding that three of the missiles and 42 drones were destroyed and another 30 drones failed to reach their targets without causing damage. The attacks came amid uncertainty over whether Kyiv will take part in a new round of peace talks early next week in Istanbul. In the Russian attacks on Saturday, a child was killed in a strike on the front-line village of Dolynka in the Zaporizhia region, and another was injured, Zaporizhia's Governor Ivan Fedorov said. The shockwave from the blast also damaged several other houses, cars, and outbuildings," Fedorov wrote on Telegram.

Large language models (LLMs) often generate content that contains factual errors when responding to fact-seeking prompts on open-ended topics. To benchmark a model's long-form factuality in open domains, we first use GPT-4 to generate LongFact, a prompt set comprising thousands of questions spanning 38 topics. We then propose that LLM agents can be used as automated evaluators for longform factuality through a method which we call Search-Augmented Factuality Evaluator (SAFE). SAFE utilizes an LLM to break down a long-form response into a set of individual facts and to evaluate the accuracy of each fact using a multi-step reasoning process comprising sending search queries to Google Search and determining whether a fact is supported by the search results. Furthermore, we propose extending F1 score as an aggregated metric for long-form factuality.

Since his first day in office, President Donald Trump has mismanaged negotiations over an end to the war in Ukraine. More than 100 days later, innocent Ukrainians are still dying while the president gets played by Russian President Vladimir Putin – illustrated starkly by the barrages of drones and missiles continually aimed at Ukrainian cities as Trump posts online. It's good to hear Trump finally express some frustration toward Putin and admit that his negotiating tactics aren't working, that, as he says, Putin is "just tapping me along, and has to be dealt with differently." The reasons for this aren't complicated. Instead of increasing his leverage over Russa, Trump offered concession after concession before talks even began.

Announcing the results of the review, the MoD said a new Digital Targeting Web would better connect soldiers on the ground with key information provided by satellites, aircraft and drones helping them target enemy threats faster. Defence Secretary John Healey said the technology announced in the review - which will harness Artificial Intelligence (AI) and software - also highlights lessons being learnt from the war in Ukraine. Ukraine is already using AI and software to speed up the process of identifying, and then hitting, Russian military targets. The review had been commissioned by the newly formed Labour government shortly after last year's election with Healey describing it as the "first of its kind". The government said the findings would be published in the first half of 2025, but did not give an exact date.
