The Refugee Council is calling for asylum seekers to be taken off the streets as a matter of urgency.
The current shortage of accommodation means some newly-arrived refugees are sleeping rough until beds become available.
However, there are renewed fears for their safety - after a fire was set alight at a tented camp in Dublin city on Friday, following an anti-immigration protest.
CEO of the Irish Refugee Council, Nick Henderson says the level of aggression is of deep concern:
"Well there were demonstrations outside direct provision centres in January and February and indeed last year."
"But there was walls separating people. It was very uncomfortable people inside but there were walls."
"We're now in a situation where there's nothing and people are in tents."
Nick concluded by calling for vulnerable people to be taken off the streets "as soon as possible."
