A jet-powered drone exploded within 4 kilometers of the border near Yahodyn-Dorohusk on September 17, forcing the scramble of fighter jets and the temporary closure of Rzeszow and Lublin airports. In response, Poland deployed the 18th and 4th Engineer Regiments to build guard posts at border crossings and ordered border guards to wear helmets and body armor. Tusk cautioned that Russian attacks on energy infrastructure will likely intensify by winter, citing monthly Ukrainian casualty figures of 27,000 killed and wounded.
