The US Embassy in Dublin has been accused of 'scaremongering' after it published warnings about a planned protest against Donald Trump's travel ban.

The 'United Against Racism' demonstration is scheduled to take place outside the embassy in Dublin at 6pm this evening.

Hundreds of people are expected to attend the event, with the embassy advising the crowd "may exceed 1,000".

A notice on the embassy's website says ''even protests intended to be peaceful can turn confrontational and escalate into violence".

The embassy warns US citizens here to "avoid areas where demonstrations are taking place and exercise caution when in the vicinity of any large gatherings, protests, or demonstrations".

Anti-Austerity Alliance TD Mick Barry will address tonight's protest, and claims the advisory is an attempt to warn-off American citizens from attending the protest.

Deputy Barry described any suggestion of a threat of violence breaking out at tonight's demonstration is "disgraceful".

He argued: "Rather than being anti-American [...] the protest is standing in solidarity with the millions of people who have taken to the streets, college campuses and airports to protest against Trump's policies." 

He explained that one of the points being made tonight will be a call for Enda Kenny to call off his St Patrick's Day trip to Washington.

"This idea that he's going to go over there and give [Donald Trump] a dressing down is nonsense - I can't really see that happening in any serious way," Deputy Barry added.
