The opening of the Government's Consultative Forum on International Security at University College Cork has been interrupted by protesters.
Before Tánaiste Micheál Martin could make his opening remarks, a number of protestors shouted "No to NATO" and unfurled a red banner saying "NATO Wars. Millions Dead."
The Tánaiste then took to the podium and said: "The most undemocratic thing you can do is trying to shut down debate. And that's what you are trying to do."
