San Francisco Frontiers - Ukraine drones strike deep in Russian territory on eve of new talks

In a spectacular claim, Ukraine said it damaged $7 billion worth of Russian aircraft parked at four airbases thousands of kilometres across the border, with unverified video footage showing aircraft engulfed in flames and black smoke.

A source in the Ukrainian security services (SBU) said the strikes hit 41 planes that were used to "bomb Ukrainian villages".

The drones were concealed in the ceilings of transportation containers that were opened remotely for the assault, the source added.

- Ceasefire talks -

The long-planned operation came at a delicate moment three years into Russia's invasion.

Ukraine's President Volodymyr Zelensky said Sunday that he was sending a delegation to Istanbul led by his Defence Minister Rustem Umerov for talks on Monday with Russian officials.

Turkey is hosting the meeting, which was spurred by US President Donald Trump's push for a quick deal to end the three-year war.

Zelensky, who previously voiced scepticism about whether Russia was serious in proposing Monday's meeting, said priorities included "a complete and unconditional ceasefire" and the return of prisoners and abducted children.

Russia, which has rejected previous ceasefire requests, said it had formulated its own peace terms but refused to divulge them in advance.

Russian Foreign Minister Sergei Lavrov and his US counterpart Marco Rubio spoke by telephone Sunday about "several initiatives aimed at a political solution to the Ukraine crisis", including Monday's talks, the Russian foreign ministry said in a statement carried by the TASS news agency.

- 'Spider's Web' -

Zelensky on Sunday hailed "brilliant" results of the coordinated attack, code-named "Spider's Web", which he said had used 117 drones and was the country's "most long-range operation" in more than three years of war.

Russia's defence ministry confirmed on Telegram that several of its military aircraft "caught fire", adding that there were no casualties.

Rybar, an account on the Telegram message platform that is close to the Russian military, called it a "very heavy blow" for Moscow and pointed to what it called "serious errors" by Russian intelligence.

The SBU source said the strikes targeted Russian airbases in the eastern Siberian city of Belaya, in Olenya, in the Arctic near Finland, and in Ivanovo and Dyagilevo, both east of Moscow.

The operation was prepared for over a year and a half, the SBU source said, and aimed to destroy "enemy bombers far from the front".

Zelensky said one of the targeted locations was right next to one of the offices of the FSB Russian security services.

- 'First such strike on Siberia' -

Russia said it had arrested several suspects, including the driver of a truck from which a drone had taken off, state agencies said.

But Zelensky said people involved in preparing the attacks were "extracted from Russian territory in time".

Igor Kobzev, governor of Russia's Irkutsk region, which hosts the Belaya airbase, said it was "the first attack of this sort in Siberia".

He called on the population not to panic and posted an amateur video apparently showing a drone in the sky and a large cloud of grey smoke.

- Russia drone strikes -

Russia has been announcing Ukrainian drone attacks on a near-daily basis, usually saying they had all been shot down.

At the same time, Russia has been carrying out constant attacks on Ukraine.

On Sunday, Ukraine's air force said it was hit by 472 Russian drones and seven missiles overnight, a record number since the beginning of the invasion in February 2022.

In a rare admission of its military losses, the Ukrainian army said Russia's "missile strike on the location of one of the training units" had killed a dozen soldiers, most of whom had been in shelters during the attack, and wounded more than 60.

The attack led Ukrainian ground forces commander Mykhailo Drapaty to announce his resignation, saying he felt "responsibility" for the soldiers' deaths.

Separately on Sunday, the Russian army said it had captured another village in Ukraine's northern Sumy region, where Kyiv fears Moscow could mount a renewed ground assault.
