A group of people are continuing to protest outside the Central Bank plaza in Dublin city centre.

The protests are under the banner of "Occupy Dame Street", which saw demonstrators set up camp outside the building on Saturday afternoon.

The group has said its mission is to end corporate corruption and keep the International Monetary Fund and European Central Bank out of Irish affairs.

The group is also demanding the return to the Irish people of oil and gas reserves off the Irish coast.

It is acting in solidarity with movements, including "Occupy Wall Street" in the US, and similarly aims to be a non-violent, leaderless resistance movement with no political affiliations.

The protests have led to heated debate in the US, with much of the criticism coming from Republican politicians.

"It's anti-American," Republican presidential candidate Herman Cain said on CBS' Face the Nation yesterday.

"Even though we have our challenges, I believe that the protests are more anti-capitalism and anti-free market than anything else."

His comments were echoed by fellow Republican presidential candidate Newt Gingrich, who said "I think the sad thing is this a natural product of (President Barack) Obama's class warfare".

But Nancy Pelosi, the Democratic leader in the House of Representatives, told ABC's This Week "I support the message to the establishment, whether it's Wall Street or the political establishment and the rest, that change has to happen.

"When we said everyone should pay their fair share, the other side (Republicans) said that's class warfare ... No, it's not. It's the most endearing American value, fairness."
