Palladium rose for a fourth straight session on Monday to a 13-1/2-year high on fears that supply from top producer Russia could be hit due to the Ukraine crisis, while gold was little changed as the dollar nudged higher.  

Spot palladium had climbed 0.8 percent to $906.50 an ounce by 0623 GMT, after earlier hitting a fresh 13-1/2-year high of $907.50.
