Police were forced to separate Celtic and Rangers supporters after fans from both teams invaded the pitch at Ibrox Stadium following Celtic's Scottish Cup quarter-final victory on Sunday.

Celtic advanced to the semi-finals after defeating Rangers 4-2 in a penalty shootout, following a 0-0 draw after 120 minutes of play in the Old Firm derby.

As the match concluded, supporters from both sides spilled onto the pitch, prompting police intervention to restore order. Flares were thrown during the disturbances, and television footage showed at least one Rangers fan approaching Celtic players on the field.

The incident marked the latest flashpoint in the historically intense rivalry between Scotland's two largest football clubs. The Scottish Cup quarter-final was played at Rangers' home ground of Ibrox in Glasgow.

Celtic's victory ensures their progression to the Scottish Cup semi-finals, while the post-match scenes overshadowed what had been a closely contested match that required extra time and penalties to determine a winner.
