 Ukraine raises stakes at war with strikes deep inside Russia. Ukraine on Monday struck two Russian air bases far from the front line, raising the stakes at the war and demonstrating its capabilities to attack at long distances. Kyiv executed the strikes using drones. The attack on the air bases was a deep strike inside Russia since the start of the invasion on February 24. Ukraine hit Angels 2 and Yagilev air bases in Russia's Ryazan and Saratov regions in what appears to be preemptive strikes on bombers that Russia deployed to cripple the country's electricity grid. Both air bases host 295 long-range bombers. The attack killed three servicemen, injured four others, and damaged two aircrafts, the Russian Defense Ministry reported. It was followed by Russia's large-scale missile strikes on Ukraine on Monday. Ukraine's ability to hit that far raises questions over its next moves, especially with regards to its Russian and next Crimea region. These questions are also relevant, as Ukraine has started manufacturing its long-range combat drones. Last month, Ukraine's state-owned weapons manufacturer Ukr-Obaronprom announced that the development of Ukrainian-made drone was being finalized. Today, the Ukr-Obaronprom issued another statement, saying that it has run a number of successful tests of the Ukrainian strike drone with a thousand kilometer range.
