Summarize this content to 2000 words in 6 paragraphs A state of emergency has been declared in Kursk after Russian authorities said Ukraine launched a rare incursion into the Russian border region.Acting regional Governor Alexey Smirnov said the “operational situation” in the border area of Kursk remained “complicated” on Wednesday, a day after Russia said Ukrainian units launched an incursion into the region.”In order to eliminate the consequences of enemy forces entering the region, I have decided to declare a state of emergency,” Smirnov said in a Google-translated update on Telegram, adding that drone and missile attacks had continued overnight.Russia’s defense ministry said Tuesday that 300 Ukrainian troops had crossed over the border with tanks and armored vehicles, entering the country near the town of Sudzha, around 400 miles southwest of Moscow. Kursk lies across the border from Ukraine’s northeastern Sumy region.Russian President Vladimir Putin on Wednesday accused Ukraine of carrying out “yet another large-scale provocation” at the Russian border, amid ongoing fighting between Ukrainian units and Russian forces sent to defend the area.Russia’s defense ministry claimed Wednesday that its forces were “destroying armed formations” using air and missile strikes, along with artillery.Valery Gerasimov, the chief of Russia’s general staff, later told Putin that Russian forces had halted an offensive undertaken by 1,000 Ukrainian soldiers — a troop estimate far higher than the original figure supplied by the country’s defense ministry.”The enemy’s advance deep into territory in the Kursk direction was stopped by the actions of the units covering the state border together with border guards and reinforcement units, with air strikes, missile and artillery fire,” Gerasimov said in televised comments reported by Reuters.The Ukrainian authorities have not made any public comment on the incursion. CNBC has requested further information from the Ukrainian defense ministry.U.S. State Department Spokesperson Matthew Miller told reporters on Wednesday that the U.S. had not been forewarned of a Ukrainian incursion, but did not appear to rule out that an offensive took place.”We did not [ know in advance about the Kursk operation]. But it’s not unusual for the Ukrainians not to notify us of their exact tactics before they execute them. It’s a war that they’re conducting. We provide them with equipment. We provide them with advice. But when it comes to the kind of day by day tactics that they carry out, the day by day strikes that they take … it’s appropriate for them to make those decisions,” he said in a press briefing.Miller said the U.S. were currently “in communication with the Ukrainians on this particular operation” but that it was inappropriate to comment on “what kind of operations they’re conducting and what their goals are. That’s appropriate that they speak to that publicly, not us.”The U.S. State Department Spokesperson further said Putin’s description of the incursion as a “provocation” was “a little bit rich … given Russia violated Ukraine’s territorial integrity and sovereignty” when it has illegally occupied Ukrainian territory since 2014, beginning with the annexation of Crimea, ahead of the largescale invasion of Feb.2022.Ukraine’s strategy, Russia’s responseUkraine’s strategy and reasons for carrying out a border raid remain unclear, although some defense analysts have commented that the operation may be an attempt to force Russia to re-deploy forces away from eastern Ukraine, where a Russian summer offensive has been gaining ground.Analysts at the Institute for the Study of War estimated Wednesday that Ukrainian forces had made confirmed advances of up to 10 kilometers — or around 6 miles — into the Kursk region “amid continued mechanized offensive operations on Russian territory.””The current confirmed extent and location of Ukrainian advances in Kursk Oblast [region] indicate that Ukrainian forces have penetrated at least two Russian defensive lines and a stronghold,” the ISW said in analysis.The ISW said that the Kremlin’s response to Ukrainian offensive activities in Kursk “has so far been contradictory, as Russian officials are attempting to balance presenting the effort as a notable Ukrainian escalation with avoiding overstating its potential implications and risking domestic discontent.””The Kremlin risks, however, discrediting itself among certain communities by seemingly dismissing the significance of the attack by framing it only as a ‘provocation.”‘The ISW noted that a number of Russian military bloggers, often critical of the war and Russia’s tactics and strategy, have heavily blasted Russia’s military command for not detecting preparations for Ukrainian offensive operations into Kursk or preventing the initiative.The deputy chairman of Russia’s Security Council and well-known hawk Dmitry Medvedev called on Russian forces to crush the Ukrainian units in Kursk.”We need to learn a serious lesson from what happened and do what Chief of the General Staff Valery Gerasimov pledged to the supreme commander-in-chief to do, that is, resolutely defeat and crush the enemy,” he stated on Telegram, according to a Google translation.
