Pink balloons used as symbol of joy after Manchester tragedy

— -- The pink balloons that Ariana Grande fans can be seen gripping following Monday night's attack at Manchester Arena have now become a symbol of joy and hope.

The bubble-gum pink balloons, which were released from the arena's ceiling as the concert was ending, are honoring the 22 victims who were killed by a suicide bomber.

The balloons have also been released at vigils held this week.
