U.S. President Barack Obama has called peace in Northern Ireland a "blueprint" for those living amid conflict around the world.
During remarks Monday to a young audience in Belfast, Mr. Obama said "The terms of peace may be negotiated by leaders, but the fate of peace is up to you."
The American president arrived in Belfast Monday after an overnight flight from Washington. He is attending a G8 summit Monday and Tuesday, likely to be dominated by the U.S. decision to arm Syrian rebels.
The summit, at an Irish resort , will bring together leaders of the world's top economies.
Mr. Obama meets Monday morning with British Prime Minister David Cameron ahead of the summit.
The U.S. leader also plans to meet Monday with Russian President Vladimir Putin for talks on the Syrian conflict. The Russian leader has supported the government of embattled Syrian leader Bashar al-Assad.
The G8 summit will also address efforts to boost the world's sluggish economies.
