The US President Barack Obama has addressed school children in Belfast ahead of the G8 summit in Northern Ireland.
Barack Obama urged the teenagers to breakdown religious barriers and take a stand against extremists that attack peace.
President Obama will join the rest of the world's most powerful leaders in Enniskillen later to discuss trade and tax at the G8 summit which is likely to be dominated by international tensions over Syria.
During his speech Barack Obama recalled his last trip to Ireland when he visited his ancestors in Moneygall, Co. Offaly.
"I even watched Michelle how to pull a pint of black - who's cheering for that?" he laughed.
"It was a magical visit, but the only problem was it was far too short - so we've been eager for a chance to return to the Emerald Isle ever since, and this time we brought our daughter's too" he added.
