London – The Ukraine Security Service (SBU) carried out a large -scale operation aimed at four Russian military airfields on Sunday, a SBU source confirmed to ABC News, which claims to have hit more than 40 military planes “that bombard the Ukrainian cities every night.”
The governors of the Russian regions of Irkutsk and Murmansk confirmed drones attacks in their respective regions. The videos shared with ABC News of the SBU showed drones attacking Olenya Airbase in Murmansk and the Belaya airfield in Irkutsk. Both house strategic aircraft of Russian bombers, including bombers with nuclear capacity.
The governor of Irkutsk said the drones were thrown from the back of a truck in the area. The governor published a drone accompanying video flying above and huge smoke columns that rise nearby.
The smoke rises above the area after what local authorities called a drone attack against a military unit in the Sredny settlement, in the Usolsky district of the Irkutsk region, Russia, in this fixed image of a video published on June 1, 2025.

A source on the SBU told ABC News that the operation had been planned for “more than a year and a half.” The drones were hidden into “mobile houses” improvised with retractable roofs, which were then placed in trucks.
“At the right time, the houses of the houses opened remotely and the drones flew to attack,” said the source.
The hidden Ukrainian drones within the “improvised mobile houses” with retractable roofs were used in Attack, on June 1, 2025, in ABC News, an ABC News security service, a Ukraine Safety Service (SBU).

In other places, at least seven people died and 66 wounds when a railway bridge collapsed and a train derailed in the western region of Bryansk in Russia during the night, after what a local official said it was “an explosion” on the route.
The Moscow Railway train operator said that the 68 passenger train was traveling from the Belgorod border city of Klimov to Moscow when it derails “due to the collapse of the highway bridge superstructure as a result of the illegal interference in transport operations.”
“There was an explosion on the bridge on the road while the Klimov-Mudú train moved, which had 388 passengers on board,” said Bryansk governor Aleksandr Bogomaz during an interview on the Rossiya-24 television channel, as cited by the State News Agency TASS.
Bogomaz said on the telegram that seven people died and 66 people were injured, 47 of which were hospitalized.
A second railway bridge collapsed during the night in the Russian region of Kursk, another neighboring border region of Bryansk north, derailing a passing train that passes.
“Part of the train fell on a road under the bridge,” said Alexander Khinshtein, the interim regional governor. At least one worker was injured, he added.
Andrei Kishas, president of the Construction Committee of the State of the Federation of the Federation of Russia, said in Telegram that Ukraine was responsible for the deadly incident in Bryansk.
“The bridge blow and the derailment of the passenger train in the Bryansk region indicate that Ukraine is controlled by a terrorist group,” he wrote.
The Kremlin said in a statement that President Vladimir Putin “was informed about the situation,” receiving updates from the Federal Security Service and the Emergency Ministry.
Andriy Kovalenko, head of the Counter-Disympration Center that operates as part of the Ukrainian National Security and Defense Council, played suggestions for Ukrainian participation in a telegram post, linking the accusations with the planned peace conversations on Monday in Istanbul, Turkey.
“It seems that the Kremlin is preparing the ground for the interruption of conversations,” Kovalenko wrote. “Ukraine has no reason to interrupt the Istanbul Summit. On the contrary, Ukraine agreed to stop the fire a long time ago. Therefore, a railway war in the style of World War II is an argument for Russian propaganda, not an instrument of our policy.”
In the past, Ukrainian intelligence services have been attributed in the past.
On Sunday, for example, Ukrainian military intelligence, Gur, reported an explosion on a railroad in southern Ukraine occupied on Saturday night, which said he derailed a cargo train that was heading towards Crimea occupied.
“As a result of an explosion on the railroad track, the train with fuel tanks and the load cars were deranged,” Gur said in a statement. “The key logistics artery of the muscovitas in the occupied territories of the Zaporizhzia and Crimea region was interrupted.”
“The fight against the military logistics of the Russian occupants continues,” added Gur’s statement.
The Ukrainian attacks in the Russian border regions of Bryansk, Kursk and Belgorod have become a common place for more than three years of the large -scale invasion of Moscow to its neighbor. These have included land raids of the Ukrainian forces, especially in the Kursk region.

Meanwhile, Moscow also continued its own long -range strike campaign against Ukraine. The Ukraine Air Force reported 479 drones and missiles thrown into the country during the night, marking one of the, if not the largest air attack of the 3 -year war.
The Air Force said it neutralized 385 of the “air attack assets”, but added that the “impacts” were recorded in 18 places.
The Ukrainian terrestrial forces also reported a Russian missile strike in a military training installation in a place not revealed in Ukraine, in which 12 people died and 60 wounds.
