What is in the 28-point US plan for Ukraine? 'Ukraine is running out of men, money and time' Can the US get all sides to end the war? Why is Europe opposing Trump's peace plan? Two people were killed in a Ukrainian drone strike on the Russian city of Saratov, regional Governor Roman Busargin said in a statement on Telegram. An unspecified number of people were also injured in the attack.

Russian attacks have left thousands without power in Ukraine, while a drone attack killed two people in Russia, as United States-led peace talks on ending the war, deep in its fourth year, press on. Ukrainian President Volodymyr Zelenskyy said Saturday that Russian night-time attacks damaged more than a dozen civilian facilities, disrupting power in seven regions. "They still aim to destroy our state and inflict maximum pain on our people." Kyiv and its Western allies have repeatedly said Russia is trying to cripple the Ukrainian power grid and deny civilians access to heat, light and running water for a fourth consecutive winter, in what Ukrainian officials call "weaponising" the cold. Russian attacks left parts of the Kherson region, including the regional capital, Kherson, without power, according to regional head Oleksandr Prokudin.

What is in the 28-point US plan for Ukraine? Why is Europe opposing Trump's peace plan? Is the fall of Pokrovsk inevitable? 'A corruption scandal may well end the Ukraine war' Here's where things stand on Saturday, November 29. Russian drones struck six locations in Kyiv's city centre and eastern suburbs early on Saturday, injuring four people, as apartment buildings and other dwellings were hit, said the head of Kyiv's military administration, Tymur Tkachenko.

Effective airfoil geometry optimization requires exploring a diverse range of designs using as few design variables as possible. This study introduces AirDbM, a Design-by-Morphing (DbM) approach specialized for airfoil optimization that systematically reduces design-space dimensionality. AirDbM selects an optimal set of 12 baseline airfoils from the UIUC airfoil database, which contains over 1,600 shapes, by sequentially adding the baseline that most increases the design capacity. With these baselines, AirDbM reconstructs 99 % of the database with a mean absolute error below 0.005, which matches the performance of a previous DbM approach that used more baselines. In multi-objective aerodynamic optimization, AirDbM demonstrates rapid convergence and achieves a Pareto front with a greater hypervolume than that of the previous larger-baseline study, where new Pareto-optimal solutions are discovered with enhanced lift-to-drag ratios at moderate stall tolerances. Furthermore, AirDbM demonstrates outstanding adaptability for reinforcement learning (RL) agents in generating airfoil geometry when compared to conventional airfoil parameterization methods, implying the broader potential of DbM in machine learning-driven design.

Is the fall of Pokrovsk inevitable? Is Trump losing patience with Putin? Will sanctions against Russian oil giants hurt Putin? Ukraine faces'exhausting battles' against Russia in Zaporizhia, Donetsk Russian forces pressed into Ukraine's eastern towns of Pokrovsk and Myrnohrad during the past week as Kyiv's military mounted a stout defence. On Tuesday, Ukraine's commander-in-chief Oleksandr Syrskii said almost half of the battles on a 1,200km (745-mile) front were happening in the two towns, claiming Russia has committed 150,000 troops - almost a quarter of its strength in Ukraine - to capturing them.

With the rapid development of LLM-based agents, there is a growing trend to incorporate agent-specific data into the pre-training stage of LLMs, aiming to better align LLMs with real-world autonomous task execution. However, current pre-training benchmarks primarily focus on isolated and static skills, e.g., common knowledge or mathematical/code reasoning, and fail to reflect model's agentic capabilities. On the other hand, agent benchmarks are typically designed for post-trained models, requiring multi-turn task execution abilities that base models struggle to support. Thus, there is a compelling need for a benchmark that can evaluate agentic potentials during pre-training and guide the model training more effectively. To address this gap, we propose APTBench, a framework that converts real-world agent tasks and successful trajectories into multiple-choice or text completion questions tailored for base models. It focuses on core agentic abilities, e.g., planning and action, and covers key agent scenarios, software engineering and deep research. Compared to existing general-purpose benchmarks, APTBench offers a more predictive signal of a model's downstream performance as an agent, while remaining significantly more lightweight and cost-effective than full-scale, end-to-end agent evaluations after post-training.

How is Russia replenishing its military? What is a'coalition of the willing'? How China forgot promises and'debts' to Ukraine How are Europe, the US pulling apart on Ukraine? A Ukrainian drone attack killed three people and injured 16 near the town of Foros on the Crimean Peninsula, the Russian-appointed head of Crimea, Sergei Aksyonov, wrote in a post on Telegram. Russia's Ministry of Defence said the attack occurred "using strike drones equipped with high-explosive payloads", in a resort area "where there are no military targets whatsoever".

Ukraine says three killed in'massive' Russian aerial attack At least three people have been killed and more than 30 injured in a massive overnight Russian aerial attack on Ukraine, President Volodymyr Zelensky says. He says regions across the country were targeted as part of a deliberate strategy to intimidate civilians and destroy our infrastructure, with one direct missile hit reported on a residential building. Ukraine's air force says Moscow launched 619 drones and missiles. Russia's defence ministry says its massive strike used precision weapons and targeted military-industrial facilities. Separately, Russia says four people were killed in a Ukrainian drone attack on the Saratov region.

Ukraine's military has said it struck an oil refinery in Russia's Saratov region in an overnight drone attack, causing explosions and destruction, according to an army statement, as daily aerial exchanges intensify with diplomatic momentum to end the war in play. Saratov's governor said on Sunday that one person was killed and several residential apartments and an industrial facility were damaged, but did not mention the oil refinery being struck. "[Ukrainian] drones are targeting … deeper into Russian territory [than] in the past, where previous attacks have been focused on the line of contact in the south and the western parts of Russia," said Al Jazeera's Osama Bin Javaid, reporting from Moscow. It is still unclear whether Ukraine's claims that it hit a refinery are true, he added. Ukraine's military also said on Sunday that it had taken back a village in the Sumy region from the Russian army, which has made significant recent gains there.
