The Russian Defense Ministry on Tuesday claimed to have destroyed the U.S.-made Patriot surface-to-air missile defense system in Kyiv.
Moscow claimed it used a hypersonic Kinzhal missile to destroy the target during an overnight strike on Ukraine, the Zvezda military news outlet reported.
According to reports by Russian state media TASS, Moscow successfully carried out high-precision sea and airstrikes on Ukrainian units and ammunition storage sites.
The reports come as Ukraine made earlier claims that it had used the same systems to down an entire barrage of Russian drones and missiles overnight – including six advanced Kinzhal missiles – hours ahead of a visit from a special envoy dispatched by China.
The wave of strikes came just over a week after Kyiv announced it had shot down a Kinzhal missile for the first time, using U.S.-supplied Patriot systems.
Ukraine's reported success in taking out dozens of Russian drones and missiles illustrates its bolstered air defenses, after a winter of systemic strikes on key infrastructure.
"Another unbelievable success for the Ukrainian Air Forces!" Defence Minister Oleksiy Reznikov said in a Twitter post.
The Defense Ministry said Ukrainian air defense systems had knocked out a total of 18 missiles, including types the Kremlin had touted as "ideal," as well as nine drones.
Beijing's special envoy, high-ranking diplomat Li Hui, is expected to arrive in Kyiv for a two-day visit, as part of a European tour to promote Beijing-led peace negotiations on the war in Ukraine.
"He's expected to meet the FM (foreign minister) and other high-ranking officials," a Ukraine government source told AFP without giving details.
Li will become the highest-ranking Chinese diplomat to visit the war-torn country since Moscow's invasion last year and his trip comes three weeks after Ukrainian President Volodymyr Zelenskyy spoke by telephone to his Chinese counterpart Xi Jinping.
Beijing has said the aim of the tour is to "communicate with all parties on the political settlement of the Ukrainian crisis."
Xi, who has aimed to position China as neutral and a would-be mediator, visited Moscow in March and has been criticized for refusing to condemn the Kremlin's war on its neighbor.
Li's visit also comes after Zelenskyy wrapped up a whirlwind tour of major European capitals to urge Ukraine's allies to increase military support.
'Like rats in a mousetrap'
His tour to shore up military assistance to help make his troops more battle ready began in Italy, with weekend visits to France and Germany, followed by a stop in the U.K.
But Zelenskyy has yet to succeed in his coveted goal of enlisting Western fighter jets to seize command of the skies, although U.K. Prime Minister Rishi Sunak announced on Monday preparations to open a flight school to train Ukrainian pilots.
France, too, has offered to train Ukrainian fighter pilots, although President Emmanuel Macron ruled out sending warplanes to Kyiv.
Nevertheless, Zelenskyy said late Monday he was "returning home with new defense packages."
On the front line, fighting has picked up in the eastern Donetsk region, in particular for the battle-scarred city of Bakhmut.
Ukraine has been posting its first gains around the city in weeks over recent days and the head of Russia's Wagner paramilitary group has blasted Moscow's performance around the key city.
The commander of Ukraine's ground forces, Oleksandr Syrskyi, said yesterday he had visited Bakhmut to hand out awards to troops fighting in the longest battle of the invasion.
"Wagner's men went into Bakhmut like rats into a mousetrap," he said.
"Using the principle of active defense, we are using counter-offensive actions in some areas near Bakhmut," he added.
The head of the Donetsk region, where Bakhmut is located, announced on Tuesday that five civilians had been killed and four more injured in fighting in the previous 24 hours.
