ALONG THE UKRAINE-BELARUS BORDER: More than four years after Russia launched its assault on Kyiv from Belarus, Ukraine is still fortifying the border it shares with Moscow's ally. What was once a busy crossing between the two countries is now a quiet, mine-laden stretch of land closed off to civilians.
Roads near the 1,084-kilometre-long (673-mile-long) border are covered for long distances by anti-drone netting. The surrounding landscape is dominated by rows of razor wire and concrete anti-tank barriers known as "dragon's teeth."
The Associated Press visited parts of the border in northern Ukraine earlier this month, following a rise in tensions between the two countries; Ukraine demanded that Belarus shut down communications relay stations Russia had installed to boost the range of its drones attacking Ukrainian cities.
Belarus obliged, according to Ukraine, and rhetoric between the two governments has eased since then. While Ukrainian officials say they see no signs of a Russian troop buildup in Belarus, they are determined to strengthen their border against any possible threat.
Belarusian President Alexander Lukashenko has repeatedly said he has no plans for his troops to enter the war unless his country is attacked. Still, people living near the border say the possibility of Belarus becoming more involved in Russia's war remains a source of anxiety.
For many residents, the extensive defenses are both a reminder of the early days of the war and a source of reassurance that Ukraine is preparing for any future scenarios.
Ukrainian border guards patrol the area around the clock using armored vehicles, drones and other surveillance systems. Ukrainian officials say the addition of more defenses will remain a priority well into the future because Belarus is Russia's closest military ally.
