Russia said the strikes were in response to "terrorist acts by the Kyiv regime", saying military sites were targeted. Moscow also reported downing 174 Ukrainian drones over parts of Russia and occupied Crimea. Russia's defence ministry said its armed forces had "launched a massive strike with high-precision long-range air, sea and ground-based weapons, as well as attack drones" on Thursday night. The attack came after Putin warned US President Donald Trump he would respond to Ukraine's recent strikes in several Russian regions. In Ternopil, military chief Vyacheslav Negoda said Friday's strike had been the "most massive air attack on our region to date", injuring five people and damaging homes and schools.
