Ukrainian sources have indicated that thousands of troops have been committed to its incursion into Russia’s Kursk province, as Moscow and Kyiv traded accusations about a fire at the occupied Zaporizhzhia nuclear power plant 250 miles to the south.
A Ukrainian security official told the Agence France-Presse that the aim of the incursion was to destabilise Russia and string out Russian forces with light, fast-moving attacks. It remains unclear how sustainable the operation will be in the medium term amid Kremlin threats that it will be snuffed out using Russian reserves.
