Sweden survived an overtime test before a 4-3 win over Slovakia today at the International Ice Hockey Federation World Championship in Denmark.

Austria beat Belarus 4-0 elsewhere in the group.

It means winless Belarus are now certain to be relegated to division one of the World Championships next year.
