Is the war entering a new phase? Video shows the moment a Russian attack hit a parking lot in Vyshneve near Ukraine's capital, causing a woman walking nearby to fall before fleeing to safety. According to authorities, it was the second consecutive day of Russian attacks on the Kyiv region.

Repeated drone strikes on oil and power infrastructure are deepening Libya's energy crisis. Al Jazeera's Malik Traina says attacks are threatening fuel supplies and worsening power cuts as rival groups compete for control of the strategically located city of Az Zawiya.

A drone has struck a power station in Libya's western city of Zawiya, near the country's largest operational oil refinery. The oil refinery has been the target of several attacks in recent days prompting the government to consider a shutdown.

Fire rages after drone strikes Libya's largest oil refinery Firefighters in Libya are battling a massive blaze at the Zawiya refinery following a drone attack, with the country's national oil company warning it may declare a force majeure and shut down operations if attacks continue. Libya's Ambulance and Emergency Service said in a statement on Tuesday there were no "serious injuries" from the fire, with most patients treated for smoke inhalation. It is located about 40km (25 miles) west of the capital, Tripoli. The National Oil Corporation (NOC) said in a statement on Facebook that the fire broke out on Monday evening at tank number 402-T, belonging to the Brega Oil Company. It said the tank, which contained about 4.5 million litres (1.2 million gallons) of gasoline, was "directly targeted, resulting in a severe fire before the tank completely collapsed".

Where did all the money go if the US is running out of weapons? Where did all the money go if the US is running out of weapons? The war on Iran is exposing shortages in US weapons stockpiles, raising questions about years of defence spending. As a former Pentagon official points out, after less than five months of fighting the US is already running out of ammunition against a'middle-tier country'.

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, ...

Multivariate Hawkes processes are a widely used class of self-exciting point processes, but maximum likelihood estimation naively scales as $O(N^2)$ in the number of events. The canonical linear exponential Hawkes process admits a faster $O(N)$ recurrence, but prior work evaluates this recurrence sequentially, without exploiting parallelization on modern GPUs. We show that the Hawkes process intensity can be expressed as a product of sparse transition matrices admitting a linear-time associative multiply, enabling computation via a parallel prefix scan. This yields a simple yet massively parallelizable algorithm for maximum likelihood estimation of linear exponential Hawkes processes. Our method reduces the computational complexity to approximately $O(N/P)$ with $P$ parallel processors, and naturally yields a batching scheme to maintain constant memory usage, avoiding GPU memory constraints. Importantly, it computes the exact likelihood without any additional assumptions or approximations, preserving the simplicity and interpretability of the model. We demonstrate orders-of-magnitude speedups on simulated and real datasets, scaling to thousands of nodes and tens of millions of events, substantially beyond scales reported in prior work. We provide an open-source PyTorch library implementing our optimizations.
