NNA – A blast rocked an optics and optical electronics factory in the town of Sergiev Posad, 50 km (30 miles) northeast of Moscow, on Wednesday, injuring at least 45 people, local authorities said.
Emergency services said the blast appeared to have occurred in a warehouse containing pyrotechnic equipment, the state news agency TASS reported. The popular online news channel Mash said it had been rented by a pyrotechnics firm.
Twenty-three people were admitted to hospital, including six in intensive care, the Sergiev Posad mayor#39;s office said.
Unverified footage on social media showed a huge column of smoke, and high-rise buildings with windows blown out. mdash; Reuters
