For more than three years, most of Russia has viewed the war sparked by the Kremlin's full-scale invasion of Ukraine from afar.

Now, some say, following an audacious attack by Ukraine that saw hordes of drones smuggled into Russia and then deployed on June 1 to wipe out dozens of long-range bombers, it has arrived on their doorstep.

In the Irkutsk, Murmansk, Ryazan, and Ivanovo regions, drones struck air bases, shocking Russian authorities and citizens.

"It was a fiery hell," residents of the Irkutsk region told RFE/RL's Siberia Realities.

In Siberia, some 4,000 km away, residents appeared to be shaken.

"Now the war has reached us too," residents told Siberia Realities.

Late on Sunday night, President Volodymyr Zelensky confirmed on social media that all of the operatives of the nation’s security services, SBU, who had participated in a a raid earlier in the day that knocked out about $7 billion in Russian military aircraft within the invading country’s airfields, were safe in Ukraine and accounted for.

The operation was dubbed “Spiderweb.”

“An absolutely brilliant result,” the president wrote.

“A result achieved solely by Ukraine. One year, six months, and nine days from the start of planning to effective execution. Our most long-range operation. Our people involved in preparing the operation were withdrawn from Russian territory in time,” Zelensky wrote on Facebook.
