Novaya Gazeta's source claims the former police station was housing Syrian government troops and Russian "military advisers." Journalists have asked the Russian Defense Ministry to comment on the reported deaths of Russian citizens in the blast.
Russian state officials have not acknowledged the presence of "Wagner" mercenaries in Syria, though journalists have reported extensively on the group's operations. The company is believed to have ties to catering magnate and close Putin ally Evgeny Prigozhin.
