Ukraine's forces advanced further into Russia's Kursk region on Wednesday as Kyiv said its gains would provide a strategic buffer zone to protect its border areas from Russian attacks.
Kyiv's surge into Russian territory last week caught Moscow by surprise. Russian forces that began a full-scale invasion of Ukraine in 2022 had been grinding out steady gains all year.
President Volodymyr Zelenskiy said he met top officials to discuss the humanitarian situation and establishing a military commandant's offices “if needed” in an occupied area that Kyiv says exceeds 1,000 sq km (390 sq miles).
"We continue to advance further in Kursk," Zelenskiy wrote on Telegram, "from one to two km in various areas since the start of the day".
Later, in his nightly address, Zelenskiy referred to the growing number of Russian prisoners of war taken in Kursk who could be exchanged for Ukrainian fighters.
"Our advance in Kursk is going well today – we are reaching our strategic goal. The 'exchange fund' for our state has also been significantly replenished."
