The Taoiseach will attend a Remembrance Sunday ceremony in Enniskillen today.
It's a tradition first begun a decade ago after the IRA bombed a ceremony being held to commemorate British military deaths.
A permanent memorial has been put in place this year, to remember the victims of what became known as the Poppy Day bombing.
The event is one of many taking place across Northern Ireland to mark the dead of two world wars.
The main commemoration south of the border will be at St Patrick's Cathedral in Dublin where President Michael D Higgins and Lord Mayor, Councillor Caroline Conroy will attend a choral service this afternoon.
