Irish Prime Minister Leo Varadkar expressed concern on Sunday after a group of vacant buildings burned down near Dublin, according to breakingnews.ie.
Demonstrations hostile to the reception of migrants had taken place there.
Some 40 firefighters were mobilized at 7 a.m. this Sunday.
In a press release, the head of government said he was “very concerned” by this fire, which comes after other incidents in the country.
“There is never any justification for violence, arson or vandalism in our Republic,” he said.
He further highlighted the profound irony that “those who try to link immigration and crime are themselves engaging in serious criminal activity.”
In December, a hotel which was to accommodate asylum seekers was already the target of an arson attack.
And at the end of November, the capital Dublin was shaken by unprecedented riots, which the authorities attributed to far-right agitators, after a knife attack which left four injured, including three children.

The government notably blamed the spread of rumors on social networks, with some Internet users claiming that the attacker was an “illegal immigrant” or an “Algerian national”.
