As an additional note: same incident on same spot happened last year with an Air Astana 320. Pilots were blamed. Atyrau is not positively known for their consciousness in maintaining their airport. For pax it is a horror. Standing outside for up to 3 hours in -29C or +30C to check in for international flights.
Clearing ice is just not done. Maybe scraping a patch of 20M with on the runway.
