Ukraine has 'advanced well' in Kursk: Zelensky

President Volodymyr Zelensky said on Wednesday that Ukrainian troops had "advanced well" into Russia's Kursk region, as Kyiv's biggest cross-border attack stretched into a second week.

The Ukrainian army entered the Kursk region on August 6, capturing dozens of settlements in the biggest offensive by a foreign army on Russian soil since World War II. "Today we have advanced well in the Kursk region. We are achieving our strategic goal," Zelensky said in his evening address.

He had also spoken of gains of "one to two kilometres (0.6-1.2 miles) in different areas since the beginning of the day" in a social media post earlier on Wednesday. Interior Minister Igor Klymenko said Ukraine would create a "buffer zone" in the region to prevent Russian cross-border strikes.
