RTE has evacuated the building that houses its TV and news studios amid a bomb scare.
It happened just after 4pm and staff had to come off air due to the threat.
Gardai were called to the scene, but staff have now been allowed back in.
The scare came as RTE Archives tweeted a link to a bomb blast at the studios in 1969.
