In pictures: President Biden visits Northern Ireland and the Republic
US President Joe Biden has been welcomed to Northern Ireland on a visit to mark the 25th anniversary of the Good Friday Agreement.
In a keynote speech at Ulster University, President Biden said he hopes for the return of power-sharing at Stormont.
He insisted stable devolved government could deliver an economic windfall for the region.
President Biden also praised the work of the UK and EU to strike the Windsor Framework on post-Brexit trading arrangements.
Belfast actor James Martin, who won an Oscar with An Irish Goodbye, was among those in the audience for President Biden's speech.
Joe Biden said he will "brag" to his daughter about meeting the celebrity.
Crowds turned out in Belfast city centre to watch the US President leave his hotel and travel to Ulster University on Wednesday morning.
There has been a large security presence around the city in the lead-up to and during Joe Biden's visit.
But despite a yellow weather warning on Tuesday evening, it proved to be a dry and sunny morning in Belfast for the day's events.
After completing his speech in Belfast, President Biden travelled on to the Republic of Ireland for the remainder of his four-day visit.
He arrived at Dublin Airport where he was greeted by Taoiseach Leo Varadkar.
Later he travelled to the town of Carlingford in Co Louth, where his great, great grandparents emigrated from in the 1800s.
Crowds gathered in the rain to greet the President as his cavalcade rolled into town.
Joe Biden went on to tour Carlingford Castle alongside Tanaiste Michael Martin during this part of his trip to the Republic.
The cavalcade stopped in Dunalk where Joe Biden took a selfie while on a walkabout through the town during his trip to the island of Ireland.
