Ukraine struck a Russian air base and an oil refinery deep inside Russia overnight from Oct. 14 to Oct. 15, 2026, effectively ending its participation in the "energy ceasefire" President Donald Trump announced four days earlier. A missile alert sounded in Russia's Voronezh region around 10 p.m. Moscow time on Oct. 14 (3 p.m. ET), and on Oct. 15 Ukraine's General Staff said six Russian Su-34 bombers at Borisoglebsk airfield had been hit.
In Russia's Ryazan region, southeast of Moscow, a drone attack set fire to a Rosneft refinery, Gov. Pavel Malkov said. Reuters described it as the first Ukrainian attack on a Russian energy facility since Trump's Oct. 11 announcement. The same night, Russia hit Ukraine's Kirovohrad region with nearly 360 drones, killing three people.
President Volodymyr Zelenskyy told the Financial Times that Ukraine's pause on refinery strikes is over, saying "We're done," while Trump called the renewed strikes "a disgrace."

What Happened
Residents of the Voronezh region filmed a large fire at Borisoglebsk late on Oct. 14 after a missile alert, according to Euromaidan Press. Ukraine's Navy said in a statement that it used the Neptune coastal missile system and that six Su-34M bombers were destroyed, Reuters reported via Al Arabiya.
The General Staff of Ukraine's Armed Forces used more cautious language on Oct. 15, saying six Su-34s "sustained varying degrees of damage" and that "explosions and a fire were recorded at the facility."
Zelenskyy narrowed the claim further. "Four Su-34 aircraft were destroyed and two more Su-34s were hit," he wrote on X, adding that "our Long Neptune missile was used," The Moscow Times reported. "Russia is dragging out the war, so our long-range operations will continue," he said.
Voronezh Gov. Alexander Gusev said air defenses intercepted 33 drones and "several jet-powered aerial targets," with debris damaging outbuildings and a car, but he did not mention the airfield, according to The Moscow Times.
Ryazan refinery
In Ryazan, Malkov said on Telegram that a drone attack caused a fire at the refinery and that "the material damage is now being assessed," with no casualties reported, Reuters reported via Internazionale. Classes were canceled at 14 schools and 25 kindergartens, according to Meduza.
Russia's Defense Ministry said the fire started "after drone debris fell onto the refinery site" according to Al Jazeera, and claimed 166 drones were intercepted overnight, per The Moscow Times. Ukraine's military had not formally claimed the Ryazan strike as of Friday morning.
Russia's strike on Kirovohrad
Over the same night, Russia launched what Raikovych called the largest attack on the Kirovohrad region since 2022, with nearly 360 drones. "Unfortunately, we had impacts at 26 locations," he said, according to UNN. Three people were killed and six injured, Meduza reported, citing emergency officials.
Nationwide, Ukraine's Air Force reported 580 drones and two Kh-59 missiles overnight, with 536 downed, according to the Institute for the Study of War.

Who's Involved
- Volodymyr Zelenskyy, President of Ukraine: Said the block on refinery strikes "is out," per Kyiv Post, and would pause again only if Ukraine received more Patriot interceptors, per The Moscow Times.
- Donald Trump, President of the United States: Told Newsmax the strikes were "a disgrace," that Ukraine has "plenty of other targets," and "I find Zelenskyy to be more difficult to deal with than Putin," per Al Jazeera.
- Sergei Lavrov, Russian Foreign Minister: Said Oct. 15 "there will be no ceasefire," according to ISW.
- Dmitry Peskov, Kremlin spokesman: Called the Ryazan strike "nothing new," per The Moscow Times.
- Kaja Kallas, EU foreign policy chief: Said "we have to pressure the aggressor to stop the war, not the victim to surrender," per Al Jazeera.
Weapons and Military Assets
- Neptune cruise missile: Ukrainian-built; Zelenskyy said the extended-range "Long Neptune" was used. The Navy and Zelenskyy confirm the weapon; its exact variant and range are not independently verified.
- Sukhoi Su-34 (NATO: Fullback): Russian two-seat fighter-bomber widely used to drop glide bombs on Ukrainian towns, according to Euromaidan Press. Ukrainian sources disagree on whether six were destroyed or damaged.
- Russian Shahed-type and jet drones: Used in the overnight and daytime attacks across Ukraine; ISW reported 90 jet-powered drones among 138 launched during daytime Oct. 15.
- Kh-59 guided missiles: Two launched overnight, per Ukraine's Air Force via ISW.
The OSINT Picture
Borisoglebsk. The air base sits about 6 kilometers east of the town of Borisoglebsk, roughly 51.37°N, 42.18°E, with a 2,500-meter runway, according to reference data. It hosts a training aviation center and front-line Su-34, Su-35S and Su-30SM units, per Defence-blog.
Before-and-after satellite images posted by the open-source account AviVector were cited by several outlets; ISW said imagery published Oct. 15 shows damage to four Su-34s, and Militarnyi reported at least four destroyed. Confidence: moderate to high that at least four aircraft were hit; the full count of six is unconfirmed. The imaging provider was not named.
A new Russian drone base. Separately, satellite images reviewed by Reuters show Russia built a major jet-drone launch base in about six weeks, about 3.5 kilometers from Millerovo air base in the Rostov region, Reuters reported via Internazionale. The site was an empty field on Aug. 31 in Planet Labs imagery; by mid-October it was laid out with eight launch pads, only some fitted with rails so far, per ThePrint.
DroneSec analyst Mike Monnik said the site could launch 100 or more jet drones in 24 hours and could be operational within weeks, "if not earlier," Reuters reported; the Kyiv Independent also reported the findings. Confidence: high, based on commercial imagery reviewed by multiple analysts.
Geopolitical Players
- Russia: Kremlin officials deny any energy truce was agreed, and Russia kept striking Ukrainian energy sites from Oct. 11 to Oct. 14 while Ukraine held off, ISW reported.
- United States: Trump says both sides agreed to the pause; Zelenskyy told Axios it "was news for me," according to Axios. Ukraine has said it received no advance warning of some Russian strikes, while Trump denies the U.S. has stopped sharing intelligence, per Kyiv Post.
- European Union: EU foreign policy chief Kaja Kallas pushed back on pressure on Kyiv during Zelenskyy's Oct. 15 visit to Brussels, per Al Jazeera.
- U.S. diesel deal: Treasury's license for Russian-origin diesel runs to April 7, 2027, TIME reported, and a bipartisan group of senators has urged reversing it.
What It Means for the United States
Benefits and opportunities
- Fewer glide-bomb aircraft: Destroyed Su-34s reduce Russia's ability to pound Ukrainian cities, which may strengthen Kyiv's position in any U.S.-brokered talks.
- Pressure on Moscow: Refinery strikes cut Russian fuel revenue, a lever Washington could use in negotiations.
- Allied burden-sharing: Europe's vocal support for Kyiv signals willingness to carry more of the cost.
Risks and dangers
- Fuel prices: Ukrainian strikes on Russian refineries can tighten global diesel markets at a time when U.S. diesel averages above $6 a gallon, according to the Energy Information Administration.
- Credibility gap (analysis): A ceasefire announced by Washington that neither belligerent observes risks undercutting U.S. mediation.
- Alliance strain: Public friction between Trump and Zelenskyy, and disputes over intelligence sharing, could fracture Western unity.
- Escalating drone warfare: Russia's rapid construction of jet-drone infrastructure shows a war industry adapting faster than Western defenses.

What's Next
- More refinery strikes: Zelenskyy has said long-range operations will continue unless Ukraine receives more Patriot interceptors.
- Damage confirmation: Further satellite imagery may settle whether four or six Su-34s were lost.
- Millerovo drone base: Analysts expect it to be operational within weeks.
- Nov. 3: U.S. midterm elections, with Ukraine policy and fuel prices both in play.
