UPPORTED by 130 bombers, dozens of tanks and heavy smoke, screens, Russian troops launched a terrific attack on Finnish positions at Summa in the middle of the Mannerheim Line this morning in an attempt to break through. Fighting continued there tonight.

Artillery preparations for the attack lasted six hours.
