Enda Kenny laid a wreath in Enniskillen, where 12 people died in an IRA bombing in 1987
The Taoiseach and Tánaiste have attended Remembrance Sunday services in Northern Ireland today.
A minutes silence was held across the UK at 11am to honour those killed in the first and second world wars and other conflicts.
Enda Kenny laid a wreath in Enniskillen, where 12 people died in an IRA bomb at the ceremony almost 30 years ago.
Frances Fitzgerald, meanwhile, is in Belfast for a ceremony at the city's Cenotaph.
The Tánaiste and Justice Minister says it is important all communities are represented at ceremonies like these.
"There are some commemorations that are unique from a particular perspective, but I think it always benefits from as much sharing as possible," she said.
Queen Elizabeth and British Prime Minister Theresa May have been leading commemorations at the Cenotaph in London - where 8,500 thousand veterans are marching.
Services have been held to remember veterans and war survivors in dozens of locations.
Meanwhile, a new France-Ireland memorial was officially dedicated in Glasnevin Cemetery.
