Omagh bombing families pledge support to victims of Manchester terror attack

Michael Gallagher lost his son Aiden, 21, and extended the hand of friendship across the Irish Sea.

Families bereaved by the Omagh bomb have supported an appeal for money for the Manchester victims.

The 1998 blast was the single most bloody attack of the Troubles and killed 29 people after a dissident republican car bomb exploded on a busy shopping street.
