Russia said on Friday that its forces had continued their assault on Ukrainian troops in the western Kursk region, while Ukraine claimed to have successfully repelled several Russian advances, inflicting heavy casualties on the Russian army.
In its statement, the Russian Ministry of Defense reported that, over the past 24 hours, its forces had killed or wounded 225 Ukrainian soldiers along the frontlines in Kursk. Russian troops also claimed to have destroyed two Ukrainian infantry fighting vehicles, three armored vehicles, five cars, and one artillery piece.
The ministry further highlighted that between Thursday night and the early hours of Friday, Russian air defense systems shot down 22 Ukrainian drones across multiple regions of Russia.
Meanwhile, Ukraine's General Staff of the Armed Forces issued an update on Friday, reporting that 138 combat engagements had occurred along the frontlines in the past 24 hours.
Ukrainian air forces, missile units, and artillery troops concentrated their strikes on Russian personnel, weapons, and equipment concentrations, claiming to have destroyed two Russian command posts and three significant military targets.
Despite the ongoing Russian offensive, Ukraine asserted that its forces had successfully repelled Russian advances in multiple directions, inflicting significant losses on the Russian side.
Ukrainian reports claimed that 1,080 Russian soldiers were killed or wounded in these clashes, with substantial amounts of Russian military equipment destroyed in the process.

China is accelerating efforts to build low-altitude infrastructure, with new takeoff and landing facilities, communication networks, and digital systems being constructed in key cities to facilitate the development of this rapidly growing sector.
Low-altitude economy refers to the economic activities and industries centered around manned and unmanned aerial vehicles operating in the airspace usually within 1,000 meters above the ground.
In southern tech hub of Shenzhen, a newly operational rooftop helipad is a key part of the city's push to expand its low-altitude economy. Originally built for fire safety, the helipad has been repurposed with plans for a new aerial sightseeing route in the surrounding area.
"We've estimated the investment, and it's relatively modest since the foundational infrastructure is already in place. The costs will likely be in the range of a few million yuan. If rooftop helipads are connected, it could create an aerial transportation network that links different buildings together," said Kuang Hu, vice chairman of Guangdong Yuehai Land Group.
Shenzhen aims to complete over 1,200 low-altitude facilities by 2026, with the local government offering subsidies of up to 2 million yuan (over 270,000 U.S. dollars) per project. These efforts are part of a broader strategy to create a seamless low-altitude infrastructure ecosystem that integrates airspace management, flight paths, and services.
"By the end of 2026, the district aims to complete 100 low-altitude infrastructure projects," said Chen Wenlei, deputy director of the Development and Reform Bureau of Luohu District, Shenzhen.
"We are in the process of establishing a comprehensive network that includes infrastructure, airspace management, flight paths, and services. By integrating these four key networks into a unified low-altitude standard system, we aim to promote the seamless opening and integration of low-altitude airspace infrastructure and systems," said Cheng Tao, executive secretary of the Shenzhen Low-altitude Economy Industry Association.
In Shanghai, the East China UAV Base has been approved for testing new drones, technologies, and services within a 1,370-square-kilometer airspace. A newly deployed 5G base station at the base offers both communication and radar-like sensing capabilities, essential for managing low-altitude airspace.
"Currently, the station covers a radius of several kilometers, offering crucial data such as the aircraft's latitude, longitude, altitude, speed, and other key metrics. Once airborne, all types of aircraft require communication. For those flying below 300 meters, we can provide tailored coverage for their flight paths," said Du Yanyan, deputy general manager of the Planning and Technology Department at China Mobile Shanghai.
Experts say that technologies like 5G and the BeiDou navigation system are essential to supporting China's low-altitude infrastructure. However, they emphasize the need for network interoperability to address challenges as drones and aircraft transition between regions.
"The low-altitude communication and sensing networks being developed in various regions each follow different technical approaches. For example, when a drone travels from Area A to Area B, it must switch networks, and addressing these challenges promptly is crucial," said Du Jiadong, head of the network and application group at the Low-altitude Economy Research Center, China Academy of Information and Communications Technology (CAICT).
The Civil Aviation Administration of China estimates that the country's low-altitude market will soar from 500 billion yuan in 2023 to 1.5 trillion yuan in 2025 and as much as 3.5 trillion yuan in 2035.
This year, for the first time, the term "low-altitude economy" was included in the Chinese government's work report, signifying an official endorsement that has emboldened numerous cities.
