The Minister for European Affairs has condemned the actions of those behind three suspect packages which were sent to transport hubs across London yesterday.
Gardaí are assisting Metropolitan Police, as it's believed at least two of the packages had Irish stamps on them.
The three small letters were found at Waterloo train station, and office buildings at Heathrow and London City airports.
The device at Heathrow 'initiated' after staff opened the package, resulting in part of the package burning.
Nobody was injured, however, and the two other packages were not opened.
A counter-terrorism investigation has been launched following the incidents.

Explosive packages
Police in the UK have warned postal and transport workers to be vigilant.
They've also said that "no passengers were put in harm’s way" by the devices.
Minister Helen McEntee said the incidents are unacceptable.
She observed: "It's completely unacceptable that that kind of action or those kind of actions would have any place in our society - whether it was intended to injure people or otherwise.
"I know the gardaí are working with the English police. Really [the incidents] need to be condemned by everybody, and whoever had done it needs to be caught and prosecuted."
