KIEV (Reuters) - A Ukrainian far right group demanded the resignation of the interior minister and said it would block roads around Kiev on Sunday in a standoff over a fatal gun battle that challenges the authority of the government.

Kiev has called on Right Sector, which played a prominent role in protests that toppled Moscow-backed President Viktor Yanukovich a year ago, to lay down their weapons after a shootout on Saturday in the town of Mukacheve killed at least two people.
