Russia has moved additional forces and equipment to the Kursk region on the border with Ukraine to protect the frontier and ensure security, regional governor Roman Starovoit said on Monday, according to Interfax news agency.
Local authorities say that the region has repeatedly been subjected to Ukrainian shelling since Russia invaded Ukraine almost a year ago.
Some of Russia's troops entered from the Kursk region, although the areas of northeastern Ukraine that they seized have since been retaken by Kyiv's forces.
