Ceremonies are taking place in Ireland and the UK for Remembrance Sunday, honouring soldiers and civilians who died in war.
President Michael D Higgins will attend a service at St Patrick's Cathedral in Dublin this afternoon.
Taoiseach Leo Varadkar, meanwhile, laid a wreath at the Cenotaph in Enniskillen earlier today.
DUP leader Arlene Foster and the British government's Northern Ireland Secretary Julian Smith also attended the event.
He also attended a service at Saint Macartin's Cathedral in the town.
12 people were killed and 63 others were injured in Enniskillen when the IRA bombed the ceremony there 32 years ago.
Former SDLP MP for South Belfast, Alasdair McDonnell says it's vital to honour those who were killed and injured.
He observed: "We're still living with the psychological scars, and indeed some people living with the physical scars of that dastardly act.
"Violence doesn't achieve anything, and all violence leaves in its wake is death and destruction.
"When the violence is over, and people ultimately have to sit around a table and recognise that others are different... that others have a different point of view."
It's 101 years tomorrow since the First World War ended with the signing of the Armistice between Germany and the Allies.
In the UK, members of the royal attended a ceremony at the Cenotaph in London to mark the occasion.
Political leaders including Boris Johnson and Jeremy Corbyn also took a break from the election campaign trail to attend the service.
