Scores of schoolchildren outside Moscow have reportedly been treated or hospitalized after exposure to foul gases that residents link to a nearby landfill.
Thousands protested against the Yadrovo landfill near the city of Volokolamsk in early March, leading to dozens of arrests.
“Twenty-three children have been hospitalized, 16 more received treatment,” an anonymous source told the Interfax news agency on Wednesday.
A Volokolamsk administration spokesperson confirmed to Interfax that a discharge of landfill gas occurred overnight.
Initial reports suggested the children were hospitalized because of an incident with pepper spray, which has been subsequently denied.
