Protestors say they will escalate their campaign if an emergency accommodation centre for asylum seekers in East Wall in Dublin isn't closed.
Demonstrators blocked the port tunnel earlier this week, with plans to continue protests every Monday, Wednesday and Friday until their demands are met.
In a statement, they say their actions are regrettable but necessary;
"We offered to work with the government on a solution and they dismissed us. Their refusal to listen to us has forced our hand."
Residents groups met with the Integration Minister Roderic O'Gorman last Friday over the newly opened housing for refugees at the former ESB office block in the area.
Malachy Steenson from the East Wall protest group says they'll be out again this evening;
"On Monday, about 400 people brought the port tunnel to a standstill by occupying a key intersection at the end of East Wall road. Tonight, and we're not going to reveal where we'll be protesting at this point, we'll be doing a similar action."
