A massive explosion rocked a factory in the Moscow region on Wednesday, injuring dozens and blowing out windows in nearby buildings, local officials said.
At least 45 people were hurt with six in intensive care as a result of the blast at the Zagorsk optical-mechanical plant in the city of Sergiev Posad, northeast of the Russian capital, the district administration said in a post on Telegram.
Videos of the blast geolocated by NBC News show a huge mushroom of smoke rising over the plant. One taken by nearby residents and posted to social media shows the moment a huge, fiery blast takes place behind a car park.
The incident happened around 10:40 a.m. local time (3:40 a.m. ET) in a pyrotechnics warehouse rented on the territory of the plant by a “private company,” Moscow Region Governor Andrei Vorobyov said on Telegram.
The Sergiev Posad district administration said there may be people trapped under the rubble. It said one area of the plant was destroyed by the blast, and others sustained partial damage.
Emergency services were now going through the debris at the plant, which has been evacuated along with a nearby kindergarten, the governor said.
People living in nearby houses had their windows shattered by the explosion, Vorobyov added, and a nearby sport complex was also partially damaged.
Vorobyov did not say what caused the blast, but Russian state media reported, citing emergency officials, that a “human factor” was behind the explosion. Local deputy Sergey Pakhomov also said “a violation of technological processes” was to blame, without elaborating.
The explosion comes amid an unprecedented number of drone attacks on the Russian capital and the surrounding region that the Kremlin has blamed on Ukraine.
Early Wednesday, Moscow Mayor Sergei Sobyanin reported that two drones were shot down by air defense systems over the capital. He said there was no information on any casualties.
