The only source provided, from El País, concerns a storm front in Catalonia, Spain, and says nothing about Russia deploying military personnel for humanitarian mine clearing in Ukraine, so that claim cannot be reported from it. The article says Spanish civil protection authorities sent an Es-Alert (a mobile phone emergency warning) to several Catalan districts, including Vallès Oriental, Maresme and Gironès, as a storm set records in Barcelona, pushed rivers toward their limits and forced evacuations in Granollers. Mosaic News cannot confirm the Russia-Ukraine demining story without a relevant source.
