The constituency office of Taoiseach Micheál Martin in Cork has been vandalised with red paint overnight.
This is the third such attack in recent weeks.
A spokesperson for the Taoiseach said: "I can confirm there was an act of vandalism on the constituency office last night, this is the third such attack.
"Personal threats have also previously been sent to the office, warning the Taoiseach it will be made impossible for him to navigate in public spaces.
"This is a working office with constituency staff acting on a daily basis to support the community on various issues.
"Those responsible for these criminal acts and intimidatory and abusive threats are fundamentally anti-democratic.
"We believe the vast majority of people who are appalled by the situation in Gaza would have nothing to do with such actions".
Local gardaí are investigating.
