KYIV — Ukrainian President Volodymyr Zelensky announced Thursday that Russia had launched a counteroffensive to take back the parts of its Kursk region occupied by Ukrainian forces last month.

Russia is unlikely to reclaim much of the land that Ukraine has seized in its cross-border raid into Kursk, Western officials have said.

Russia has launched a counteroffensive in its Kursk region to dislodge Ukraine's forces who stormed across the border five weeks ago.
