Gardaí are investigating after a memorial wall in Glasnevin cemetery was vandalised.
It commemorates those who died in the Irish revolution.
Detectives are reviewing CCTV footage of the incident, which happened in the early hours of Tuesday morning.
Intruders used sledgehammers and threw paint over the memorial wall which includes names of all those who died in the Easter Rising in 1916 to the end of the Civil War in 1923.
The vandals removed the names of the British soldiers who were killed during this time, according to the Irish Times.
But in doing so they also damaged the names of some of the Irish volunteers who were killed.
The wall was unveiled in 2016 to mark the centenary of the Rising. It's the second time the memorial has been targeted.
