An explosion at an optics and optical electronics factory in Sergiev Posad, northeast of Moscow, injured at least 60 people on Wednesday, local officials said. The rescue service said the explosion appeared to be in a warehouse containing pyrotechnic devices, state news agency TASS reported. 23 people were taken to hospital, six of them in intensive care, said the mayor of Sergiev Posad. The plant produces optical equipment for industrial and health applications as well as for the Russian security forces.
Some Russian media said the explosion was the result of a drone strike, but several Russian officials, including Vorobyov and the Russian Investigative Committee, denied this. Earlier in the day, officials said Russian air defenses shot down two drones targeting Moscow overnight in what they described as Ukraine's latest attempt to strike the Russian capital in an apparent campaign to unsettle Muscovites and take the war to Russia. Mayor Sergei Sobyanin said the drones were intercepted as they approached Moscow.
