President Volodymyr Zelenskyy of Ukraine gave no indication Friday that his country’s soldiers would withdraw from Kursk, let alone surrender.

Russian troops have breached a Ukrainian defensive line near Sudzha in the Kursk region, intensifying pressure on Ukrainian forces operating near the border and threatening a critical supply route used by Kyiv's forces.
