Ukrainian missile firing exercises have been launched in the Kherson region, spokesman for the Ukrainian Air Force's 'South' Air Command Volodymyr Kryzhanovsky said. "The firing exercises have already begun. Everything is going according to plan. There has been no reaction from the Russian Federation. The Ukrainian military is ready for any scenario," he told the 112.Ukraine TV channel. Crews operating combat and transport airplanes of the Ukrainian Armed Forces' Air Force, units of the air defense and liaison forces, as well as the Ukrainian Armed Forces' drone aviation will take part in the exercises, he said. S-300 surface-to-air missile systems will participate in them as well. Ukraine is not committing any violations by holding such live-fire exercises and is not posing any threat to the Crimean peninsula, Kryzhanovsky said. "Ukraine is not violating anything. If one looks at the trajectory and the designated district and draws an imaginary line from the peninsula, where the systems will be stationed, to Bulgaria, it will be possible to see that the outermost line will pass quite far from the coast of the Crimean peninsula. The missiles' closest approach can be no more than 30 kilometers," Kryzhanovsky said.
