A British SkySpyke anti-drone system by Quell is seen during the international military exercise Baltic Trust 25 at the Selonia military training ground near Viesite, Latvia, on Aug. 27. The proliferation of uncrewed systems in the Ukraine-Russia war has highlighted the importance of drone defense capabilities. But the dilemma militaries around the world face is that the attack weapons tend to be far cheaper than the response to destroy them. Drone costs can range from just a few hundred to several thousand dollars, and their price tag is rapidly depreciating as innovation and mass production pick up. Efforts to solve that conundrum were on display this week at the DSEI defense expo in London, where the halls were packed with lasers, missiles, jammers and even other drones designed to defeat small, uncrewed threats. What they all had in common was an attempt to bring down the cost per kill."

More Nato countries will move their troops and fighter jets eastwards after Poland accused Russia of an unprecedented drone incursion on Wednesday. Denmark, France and Germany have joined a new mission to bolster the military alliance's eastern flank. Other Nato allies are expected to take part later. It came as the Kremlin said on Friday that peace talks with Kyiv were on pause, with spokesman Dmitry Peskov saying: You can't wear rose-tinted glasses and expect that the negotiation process will yield immediate results. Political tensions have been high across Europe after Poland said 19 Russian drones had flown through its airspace on Wednesday.

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? An early morning Russian attack on Friday killed three people in northern Ukraine's Sumy region, a regional official reported. Ukrainian President Volodymyr Zelenskyy said Moscow's attempts to advance in the Sumy area had failed with heavy losses, and Russian operations in the region were being "completely foiled by our forces".

NATO to beef up defense of Europe's eastern flank after Poland drone incursions NATO Supreme Allied Commander Europe Gen. Alexus G. Grynkewich speaks during a news conference on the violation of Polish airspace by Russian drones, at the NATO headquarters in Brussels on Friday. BRUSSELS/WARSAW/UNITED NATIONS - NATO announced plans to beef up the defense of Europe's eastern flank on Friday, two days after Poland shot down drones that had violated its airspace in the first known action of its kind by a member of the Western alliance during Russia's war in Ukraine. At the United Nations, the United States called the airspace violations alarming and vowed to defend every inch of NATO territory, remarks that appeared aimed at assuaging Washington's NATO allies after President Donald Trump said Russia's drone incursion could have been a mistake. Warsaw has portrayed the drone incursions as an attempt by Russia to test the capabilities of Poland and NATO to respond. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

The white armoured police van speeds into the eastern Ukrainian town of Bilozerske, a steel cage mounted across its body to protect it from Russian drones. They'd already lost one van, a direct hit from a drone to the front of the vehicle; the cage, and powerful rooftop drone jamming equipment, offer extra protection. But still, it's dangerous being here: the police, known as the White Angels, want to spend as little time in Bilozerske as possible. The small, pretty mining town, just nine miles (14km) from the front line, is slowly being destroyed by Russia's summer offensive. The local hospital and banks have long since closed.

Ukraine has struck Russia's largest oil terminal on the Baltic Sea during one of its biggest overnight drone attacks in months. The aerial assault targeted the Primorsk oil port in the Leningrad region, the final station of the Baltic Pipeline System and a crucial hub for Russia's maritime exports, Ukraine's security services told multiple outlets. More than half of the 221 drones sent to Russian territory were intercepted over the Bryansk and Smolensk regions, where Lukoil facilities were also reportedly targeted, the Russian defence ministry said. Meanwhile, officials said two civilians were killed in Ukraine's Sumy region when a Russian glide bomb struck a village near the border. Authorities in the Leningrad region said 28 drones were brought down and that a fire had broken out at a vessel and a pumping station in Primorsk.
