Russia's largest airports experienced hours-long flight delays and cancellations on July 5, as authorities imposed temporary restrictions due to a reported threat of Ukrainian drone attacks, the pro-Kremlin Telegram channel Shot reported.

Ukraine hasn't commented on the report. Kyiv's drone campaign, which has increasingly disrupted civilian air travel in Russia, is part of Ukraine's broader strategy to undermine Russia's logistics far beyond the front line.

Some passengers in Russia reported waiting more than 10 hours on July 5 as their flights were being delayed, according to Shot.

Departures at Moscow's Sheremetyevo Airport were halted for several hours, delaying over 20 flights. At St. Petersburg's Pulkovo Airport, roughly 50 flights were delayed and more than 20 canceled.

Leningrad Oblast Governor Alexander Drozdenko said that two drones were shot down south of St. Petersburg, prompting a temporary suspension of operations at Pulkovo Airport.

The disruptions followed a wave of Ukrainian drone attacks overnight, which targeted military and industrial infrastructure in at least six Russian regions.

The Russian Defense Ministry said it intercepted 42 drones within three hours, mainly over the Belgorod, Bryansk, and Kursk oblasts near the Ukrainian border.

Novaya Gazeta Europe reported in May that at least 217 temporary airport closures have occurred across Russia since Jan. 1 due to drone threats, more than in 2023 and 2024 combined.

A similar wave of strikes ahead of Russia's Victory Day in May led to massive delays, affecting an estimated 60,000 travelers.

Ukraine’s new drone strategy — cripple Moscow’s airports, make Russian population ‘pay’

Hundreds of Ukrainian kamikaze drones have flown towards Moscow in recent weeks. None appear to have even reached the Russian capital, yet the effect on the city — and the wider country — has been hugely significant. Ukrainian drones have forced at least 217 temporary airport closures across Russia since Jan. 1,

Ukraine targeted the Borisoglebsk airfield in Russia's Voronezh Oblast overnight on July 5, damaging a warehouse with guided bombs, aircraft, and other military assets, Ukraine's General Staff reported.

The airfield hosts Su-34, Su-35S, and Su-30SM jets thatRussia regularly uses in air strikes against Ukraine, according to the military. The strike may have destroyed a training and combat aircraft, with further assessments underway.

The NASA Fire Information for Resource Management System (FIRMS) detected a fire near the Borisoglebsk military airfield shortly after the strike. Residents in the area reported 8–10 powerful explosions around 2 a.m. local time, according to Russian independent outlet Astra.

The strike was part of a broader overnight drone campaign across Russia, with explosions and fires reported in at least six regions.

The Russian Defense Ministry said 42 drones were intercepted within a three-hour period, most of them over Belgorod, Bryansk, and Kursk oblasts, which border Ukraine.

Leningrad Oblast Governor Alexander Drozdenko said two drones were downed south of St. Petersburg, prompting a temporary suspension of flights at Pulkovo airport. No casualties or damage were reported.

The governor of the Smolensk Oblast in western Russia said anti-aircraft units downed three drones without casualties or damage. The governor of the Voronezh Oblast, bordering Ukraine, also confirmed the destruction of several drones.

Explosions were also heard overnight in Cheboksary, the capital of the Chuvash Republic, where video footage shared online showed a fire reportedly at a local industrial site.

Additionally, explosions were heard during the night in Engels, Saratov Oblast, with some Telegram channels suggesting a military airfield was likely targeted.

The attacks come as Russia escalates aerial assaults on Ukraine, prompting Kyiv to increase long-range drone strikes on Russian military targets.

Ukrainian officials say these drone operations aim to undermine Russia's strike capabilities and bring the war closer to those enabling the Kremlin's campaign.
