Its important to wait until enough information is gathered. Plenty of misinformation spreads in the first hours. You do run the conspiracy sub, after all. The availability bias works against us. Mentioning that the terrorists were aided by country X or Y can be harmful. Its like saying "experts believe" or "it has been reported that..." A much smaller percentage of readers read the corrections. We need to get it right the first time by putting in enough effort and doing thorough research before spreading statements.

I don't have strong information yet, but did watch the field interrogations from the suspects. They're from Tajikistan and were contacted off of Telegram and offered money. Anyone's guess beyond that atm, but there's plenty of hard feelings towards Russia/Putin from many in the region.
