Celtic defeated Glasgow Rangers in the Old Firm derby in Scotland on penalties after a 0-0 draw in regular time. The match was the first in seven years to allow away supporters. After Celtic's Tomas Cvancara scored the decisive penalty, hundreds of supporters from both teams reportedly stormed onto the pitch at Rangers' home ground, Ibrox.
Flares were thrown between the crowds before police and stewards formed a human wall to push back the supporters. The Scottish Football Association has condemned the behavior and launched an investigation. It is unclear if anyone was injured in the disturbances.
Celtic advances to the semifinals of the Scottish Cup.
