Ukraine destroys 40 aircraft deep inside Russia ahead of peace talks in Istanbul

KYIV, Ukraine (AP) — A Ukrainian drone attack has destroyed more than 40 Russian planes deep in Russia’s territory, Ukraine's Security Service said on Sunday, while Moscow pounded Ukraine with missiles and drones just hours before a new round of direct peace talks in Istanbul.

A military official, who spoke with The Associated Press on condition of anonymity to disclose operational details, said the far-reaching attack took more than a year and a half to execute and was personally supervised by Ukrainian President Volodymyr Zelenskyy.

In his evening address, Zelenskyy said that 117 drones had been used in the operation. He claimed the operation had been headquartered out of an office next to the local FSB headquarters. The FSB is the Russian intelligence and security service.

The military source said it was an “extremely complex” operation, involving the smuggling of first-person view, or FPV, drones to Russia, where they were then placed in mobile wooden houses.

“Later, drones were hidden under the roofs of these houses while already placed on trucks. At the right moment, the roofs of the houses were remotely opened, and the drones flew to hit Russian bombers,” the source said.

Social media footage shared by Russian media appeared to show the drones rising from inside containers while other panels lay discarded on the road. One clip appeared to show men climbing onto a truck in an attempt to halt the drones.

The drones hit 41 planes stationed at military airfields on Sunday afternoon, including A-50, Tu-95 and Tu-22M aircraft, the official said. Moscow has previously used Tupolev Tu-95 and Tu-22 long-range bombers to launch missiles at Ukraine, while A-50s are used to coordinate targets and detect air defenses and guided missiles.

The Security Service of Ukraine said that the operation, which it codenamed “Web”, had destroyed 34% of Russia's fleet of air missile carriers with damages estimated at $7 billion. The claim could not be independently verified.

Russia's Defense Ministry in a statement confirmed the attacks, which damaged aircraft and sparked fires on air bases in the Irkutsk region, more than 4,000 kilometers (2,500 miles) from Ukraine, as well as the Murmansk region in the north, it said. Strikes were also repelled in the Amur region in Russia's Far East and in the western regions of Ivanovo and Ryazan, the ministry said.

U.S. Defense Secretary Pete Hegseth was briefed on Ukraine’s attack Russia during a stop at Nellis Air Force Base and was monitoring the situation. A senior defense official said on the condition of anonymity to discuss sensitive matters that the U.S. was not given notification before the attack. The official said it represented a level of sophistication the U.S. had not seen before.

Also on Sunday, Russia’s top investigative body said that explosions had caused two bridges to collapse and derailed two trains in western Russia overnight, killing seven in one of the incidents and injuring dozens more. Russian officials, however, did not say what had caused the blasts and the word “explosions” was later removed from an Investigative Committee press release.

The drone attack came the same day as Zelenskyy said Ukraine will send a delegation to Istanbul for a new round of direct peace talks with Russia on Monday.

In a statement on Telegram, Zelenskyy said that Defense Minister Rustem Umerov will lead the Ukrainian delegation. “We are doing everything to protect our independence, our state and our people,” Zelenskyy said.

Ukrainian officials had previously called on the Kremlin to provide a promised memorandum setting out its position on ending the war before the meeting takes place. Moscow had said it would share its memorandum during the talks.

Russia on Sunday launched the biggest number of drones — 472 — on Ukraine since the full-scale invasion in February 2022, Ukraine’s air force said.

Russian forces also launched seven missiles alongside the barrage of drones, said Yuriy Ignat, head of communications for the air force. Earlier Sunday, Ukraine’s army said at least 12 Ukrainian service members were killed and more than 60 were injured in a Russian missile strike on an army training unit.

Ukrainian army commander Mykhailo Drapatyi later Sunday submitted his resignation following the attack. He was a respected commander whose leadership saw Ukraine regain land on the eastern front for the first time since Kyiv's 2022 counteroffensive.

The training unit was located to the rear of the 1,000-kilometer (620-mile) active front line, where Russian reconnaissance and strike drones are able to strike. Ukraine’s forces lack troops and take extra precautions to avoid mass gatherings as the skies across the front line are saturated with Russian drones looking for targets.

ALEPPO, Syria (AP) — First responders on Sunday entered a contested neighborhood in Syria’ s northern city of Aleppo after days of deadly clashes between government forces and Kurdish-led forces. Syrian state media said the military was deployed in large numbers.

The clashes broke out Tuesday in the predominantly Kurdish neighborhoods of Sheikh Maqsoud, Achrafieh and Bani Zaid after the government and the Syrian Democratic Forces, the main Kurdish-led force in the country, failed to make progress on how to merge the SDF into the national army. Security forces captured Achrafieh and Bani Zaid.

The fighting between the two sides was the most intense since the fall of then-President Bashar Assad to insurgents in December 2024. At least 23 people were killed in five days of clashes and more than 140,000 were displaced amid shelling and drone strikes.

The U.S.-backed SDF, which have played a key role in combating the Islamic State group in large swaths of eastern Syria, are the largest force yet to be absorbed into Syria's national army. Some of the factions that make up the army, however, were previously Turkish-backed insurgent groups that have a long history of clashing with Kurdish forces.

The Kurdish fighters have now evacuated from the Sheikh Maqsoud neighborhood to northeastern Syria, which is under the control of the SDF. However, they said in a statement they will continue to fight now that the wounded and civilians have been evacuated, in what they called a “partial ceasefire.”

The neighborhood appeared calm Sunday. The United Nations said it was trying to dispatch more convoys to the neighborhoods with food, fuel, blankets and other urgent supplies.

Government security forces brought journalists to tour the devastated area, showing them the damaged Khalid al-Fajer Hospital and a military position belonging to the SDF’s security forces that government forces had targeted.

The SDF statement accused the government of targeting the hospital “dozens of times” before patients were evacuated. Damascus accused the Kurdish-led group of using the hospital and other civilian facilities as military positions.

On one street, Syrian Red Crescent first responders spoke to a resident surrounded by charred cars and badly damaged residential buildings.

Some residents told The Associated Press that SDF forces did not allow their cars through checkpoints to leave.

“We lived a night of horror. I still cannot believe that I am right here standing on my own two feet,” said Ahmad Shaikho. “So far the situation has been calm. There hasn’t been any gunfire.”

Syrian Civil Defense first responders have been disarming improvised mines that they say were left by the Kurdish forces as booby traps.

Residents who fled are not being allowed back into the neighborhood until all the mines are cleared. Some were reminded of the displacement during Syria’s long civil war.

“I want to go back to my home, I beg you,” said Hoda Alnasiri.
