TALLINN, Estonia (AP) — An explosion on the grounds of a factory that makes optical equipment for Russia's security forces injured 56 people Wednesday north of Moscow, six of them severely, officials said.
The blast occurred at a warehouse storing fireworks but was on the grounds of the Zagorsk optics manufacturing plant, Andrei Vorobyov, the governor of the region surrounding the Russian capital, said. The explosion damaged 38 apartment buildings and prompted an evacuation of nea rby areas, he said.
the surrounding area, the regional governor said. Five people were feared trapped under rubble.
Vorobyov said the company rented out the warehouse for storage, but he later claimed the plant itself was mostly producing pyrotechnics. He said the Zagorsk Optical-Mechanical Plant “has had nothing to do with optics or mechanics for a long time.”
The company's website says it still manufactures those products, as well as medical equipment. A 1995 report by the U.S. Department of Commerce described the factory as “a producer of precision optical equipment for the military.”
Russian investigative news outlet Agentstvo reported Wednesday that state procurement data from recent years showed the plant supplied binoculars and dosimeters to Russia’s National Guard, produced equipment for military aircraft and was involved in the development of a new fighter-bomber.
Russian authorities feared five people were missing in the aftermath of the explosion. Emergency crews with sniffer dogs walked over the rubble of low brick buildings, video from the scene showed. Firefighters hosed down the mangled industrial wreckage.
Russian officials did not provide a suspected cause of the explosion, which produced a tall plume of black smoke and added to jitters over recent nighttime drone attacks on Moscow. Earlier, officials said Russian air defenses shot down two drones aimed at the capital overnight, and they accused Ukraine of an attempted attack.
Some Russian media reported that a drone attack caused the blast at the manufacturing plant site. Multiple Russian authorities, including Vorobyov and Russia’s Investigative Committee, denied that.
The Investigative Committee, Russia’s top law enforcement agency, said in a statement it has launched a criminal inquiry on charges of violating industrial safety requirements at hazardous production facilities.
Russian officials described the downed drones as Ukraine’s latest attempt to strike the Russian capital in an alleged campaign to unnerve Muscovites and take the war in Ukraine to Russia.
The drones were intercepted on their approach to Moscow and there were no casualties, Mayor Sergei Sobyanin said. The Russian Defense Ministry described the incident as a “terrorist attack.”
One of the drones came down in the Domodedovo district south of Moscow, and the other fell near the Minsk highway west of the city, according to Sobyanin. Moscow Domodedovo Airport is one of the Russian capital's busiest airports.
It wasn't clear where the drones were launched, and Ukrainian officials made no immediate comment. Ukraine usually neither confirms nor denies such attacks.
Flights were briefly halted at Moscow’s Vnukovo airport on July 30 and Aug. 1, when drones smashed into Moscow's business district after being jammed by air defenses in two separate incidents.
In May, Russian authorities accused Ukraine of attempting to attack the Kremlin with two drones in an effort to assassinate President Vladimir Putin. Recent drone attacks have aimed at targets from the Russian capital to the Russia-annexed Crimean Peninsula.
In another incident that caused alarm, Ukrainian media reported social media blogs as saying that a thick plume of smoke billowed over Sevastopol.
The Moscow-appointed governor of Sevastopol, Mikhail Razvozzhayev, said the smoke came from a “fleet training exercise” and urged local residents not to worry.
“Yes, the smell is unpleasant, but it is absolutely safe,” he said on Telegram. “Everything is calm in the city.”
Those incidents occurred against the backdrop of Ukraine’s ongoing counteroffensive, which Ukrainian and Western officials have warned will be a long slog against the Kremlin’s deeply entrenched forces.
Russia is pushing back against the Ukrainians in eastern areas, where tough battles are taking place, Hanna Maliar, Ukraine’s deputy defense minister, said Wednesday on her official Telegram channel.
“In some parts of the front-line multiple changes in position take place within a day,” she said.
She claimed that Ukraine’s efforts had achieved “partial success” in the south. She gave no details.
It wasn't possible to independently verify either side’s claims.
