Russian President Vladimir Putin has ordered an inquiry into whether enough was done to prevent mass deaths in the southern flood-hit Krasnodar region.
Mr Putin demanded to know how much warning people had been given about the impending disaster.
The BBC's Oleg Boldyrev says "a very thick layer of mud" covers everything, making any clean-up operation "unfathomable".
