US President Joe Biden's trip to Ireland and Northern Ireland begins this evening.
President Biden is due to touch down in Belfast marking the start of a four day visit.
The US President will visit Belfast to mark 25 years since the signing of the Good Friday Agreement.
British Prime Minister Rishi Sunak is expected to greet the US President off the steps of Air Force One.
His one big public engagement in Northern Ireland will be at Ulster University on Wednesday when President Biden will give a speech.
Immediately after that he's due to fly to Dublin and is expected to visit Co Louth on Wednesday evening where he may do a walkabout in Dundalk.
A massive security operation is underway here in Northern Ireland where the PSNI was already on high alert amid the threat of dissident activity around the anniversary of the Good Friday Agreement.
