“Dog specialists work at the site, dogs check the presence of victims under the rubble. According to our information, presumably, people may be under the rubble ... We assume that there may be up to four people, ”RIA Novosti quotes Yevgeny Daineko, head of the Emergencies Ministry's Leningrad Region Office.
He added that, according to one of the versions, the explosion could have occurred due to a violation of the technological process in the production of pyrotechnic products.
On October 19, an explosion occurred at the Avangard pyrotechnic plant in the Leningrad Region, which killed at least two people.
