Hello, this is Tania Myronyshena reporting from Kyiv on day 1,388 of Russia's full-scale invasion of Ukraine.

Today's top story so far:

Ukrainian Defense Forces have encircled Russian troops in Kupiansk, Kharkiv Oblast, and cleared its northwestern outskirts, the open-source intelligence group DeepState reported on Dec. 12.

Later that day, the 2nd National Guard Corps "Khartia" confirmed it had led the operation, which was launched to stabilize the front following a renewed Russian offensive in the area in September.

Kupiansk, a key logistics hub located 104 kilometers east of Kharkiv, has been the focus of intensified Russian assaults in recent months. The city has remained closed to civilians since late September due to continuous shelling and the threat of Russian sabotage groups operating behind the lines.

"The operation remains difficult and prolonged, as Russian enclaves still exist in the central part of the city. There is already a significant amount of visual evidence online confirming the successful actions of Ukraine’s Defense Forces, which is why we are now publishing information that is safe to disclose," DeepState said.

On the same day, President Volodymyr Zelensky visited troops in the area.

"Many Russians boasted about Kupiansk — now we see the real result. I was here today, I met the guys, and I thanked every unit fighting here," Zelensky said in an official statement on Telegram.

In November, Russian General Staff Chief Valery Gerasimov claimed that Russian forces had captured Kupiansk. Ukrainian officials dismissed the claim as a "cheap provocation." The current Ukrainian counteroffensive appears to have disproven those claims.

Kupiansk was initially occupied by Russian forces during the early stages of the full-scale invasion, but was liberated by Ukraine in September 2022 as part of a broader counteroffensive in Kharkiv Oblast.

Russian forces launched a drone strike on civilian infrastructure in Shostka, Sumy Oblast, targeting a local sports school where children were in the middle of a training session. The attack involved two strike drones, according to Sumy Oblast head Oleh Hryhorov.

"It was a deliberate strike on a location where children were present. Two drones were directed at the site," Hryhorov reported.

All children and coaches were safely evacuated, with no injuries reported.

Speaking to Suspilne, coach Liliya Trofymenko described the moment the drone hit: "We heard the Shahed and then immediately an explosion. There was no air raid alert. The kids were training in a ground-floor hall. Luckily, they were under the trampoline by the wall. We managed to evacuate everyone and even grabbed their belongings."

The developing story is available on Suspilne.

One of Russia’s largest oil refineries ablaze amid reported Ukrainian drone strike on Yaroslavl

Last updated 4:31 p.m. Kyiv time.

Russia’s Slavneft-YANOS oil refinery in Yaroslavl, one of the country’s five largest, is reportedly on fire after being struck in an overnight drone attack on Dec. 12, officials and local Telegram channels said.

Residents reported at least seven explosions over the city, followed by reports of a fire at the Slavneft-YANOS refinery, located more than 700 kilometers (435 miles) from the Ukrainian border.

Open-source intelligence (OSINT) said the facility was struck, while Yaroslavl Governor Mikhail Yevrayev had earlier warned of a drone threat in the region.

Astra, an independent Telegram channel based in Russia, posted photos and video of an ongoing fire at the facility on the morning of Dec. 12.

The Slavneft-YANOS plant is a major producer of fuels including gasoline, diesel and jet fuel, with a processing capacity of about 15 million tons of crude per year.

Multiple other regions were targeted throughout the night, including Tver, Smolensk, and Moscow. In Tver, a drone explosion damaged the lower floors of a residential building and injured seven people, according to local authorities.

Europe must prepare for war with Russia, NATO chief warns

Last updated 4:19 p.m. Kyiv time.

Europe must prepare itself for a full-scale armed conflict as it is "Russia's next target," NATO Secretary General Mark Rutte said on Dec. 11.

"We must be prepared for the scale of war our grandparents and great-grandparents endured," Rutte said in a speech in Berlin, warning that Europe is "already in harm's way."

The NATO chief reiterated that Moscow could be ready for a war with the alliance within five years, echoing concerns of other Western officials voiced since the start of the full-scale invasion of Ukraine in 2022.

The worries were only further fueled by Russian warplanes and drones violating allied airspace and escalating cases of sabotage, cyberattacks, and espionage linked to Russian intelligence services over the past months.

Rutte said that "conflict is at our door" as "Russia has brought war back to Europe." He also warned against complacency in the face of this growing threat, urging stronger support for Ukraine and a rapid increase in defense spending and production.
