A large-scale Ukrainian drone strike on Russia on Wednesday resulted in an earthquake-sized detonation at a major armoury in the Tver area, causing the evacuation of a nearby town, according to war bloggers and certain media.
Unverified footage and photographs on social media showed a massive ball of flame bursting into the night sky and many detonations booming across a lake some 380 kilometres (240 miles) west of Moscow.
NASA satellites picked up intense heat sources emanating from an area of about 14 square kilometres (5 square miles) at the site in the early hours and earthquake monitoring stations picked up what sensors thought was a small earthquake, opens new tab in the area.
“The enemy hit an ammunition depot in the area of Toropets,” said Yuri Podolyaka, an Ukrainian-born, pro-Russian military blogger.
“Everything that can burn is already burning there (and exploding).”
There was no information about casualties.
Russian state media have in the past reported that a major arsenal for conventional weapons was located at the site of the blasts. State media, which is now subject to military censorship laws, was muted in its reporting on Wednesday.
Igor Rudenya, the governor of the Tver region, said that Ukrainian drones had been shot down, that a fire had broken out and that some residents were being evacuated. He did not say what was burning.
One woman told Reuters that members of her family had been evacuated from Toropets.
“A fire started with explosions,” the woman said, giving only a first name, Irina.
A source in Ukraine’s SBU state security service told Reuters the drone attack destroyed a warehouse storing missiles, guided bombs and artillery ammunition. There was no immediate comment from the Ukrainian government.
Russia and Ukraine each reported dozens of enemy drone attacks on their territory overnight, with Russian forces advancing in eastern Ukraine.
MAJOR EXPLOSION
The size of the main blast shown in the unverified social media video was consistent with 200-240 tons of high explosives detonating, according to George William Herbert of the Middlebury Institute of International Studies at Monterey in California.
A Toropets chatroom on the Russian social media site VK was flooded with messages of support from other parts of the country and offers of help to people fleeing the town.
Some people were asking whether buildings at specific addresses were still standing.
“People, does anyone know what’s happened to Kudino village??? They told me nothing is left of our house,” posted one woman.
Another woman replied: “It’s horror there.” Kudino is a village 4.5 km (2.8 miles) northeast of Toropets.
Some war bloggers questioned how drones could trigger such large explosions at what was thought to be a highly fortified facility.
According to an RIA state news agency report from 2018, Russia was building an arsenal for the storage of missiles, ammunition and explosives in Toropets, a 1,000-year-old town, which has a population of just over 11,000.
Dmitry Bulgakov, then a deputy defence minister, told RIA in 2018 that the facility could defend weapons from missiles and even a small nuclear attack. Bulgakov was arrested earlier this year on corruption charges. He denies the charges.
“It (the concrete facilities) ensures their reliable and safe storage, protects them from air and missile strikes and even from the damaging factors of a nuclear explosion,” RIA quoted Bulgakov as saying at the time.
Some Russians on chat groups expressed anger.
“Why wasn’t the ammunition underground?! What are you doing???? In Kudino, houses were blown away! Why is the forest burning and no one is there… what kind of negligence is this!!!!” one woman posted.
Russia reported that its air defence units had destroyed 54 drones launched against five Russian regions overnight, without mentioning Tver. Ukraine said it had shot down 46 of 52 drones launched by Moscow overnight and that Russia had used three guided air missiles which did not reach their targets.
