Taoiseach Enda Kenny said today that the removal of bin Laden's ability to plot heinous acts is a major achievement in the effort to rid the world of the threat of terrorism.
Mr Kenny said the international community cannot let up in its efforts to address the threat that terrorism continues to pose for us all.
He said Ireland will continue to work within the framework of the UN, the EU and the broader international community to address the 'scourge of terrorism and its root causes.'
Meanwhile, the Minister for Tourism, Transport and Sport, Leo Varadkar, said he does not think the killing of Osama bin Laden will have any implications for the impending visit of the US President to Ireland.
The necessary security arrangements have been put in place for Barack Obama's visit which is due to take place later this month, he said.
British Prime Minister David Cameron said earlier today that bin Laden's death would 'bring great relief to people across the world'.
'Osama bin Laden was responsible for the worst terrorist atrocities the world has seen,' Mr Cameron said in a statement.
'It is a great success that he has been found and will no longer be able to pursue his campaign of global terror.'
European Parliament President Jerzy Buzek said: 'We have woken up in a more secure world.'
President Nicolas Sarkozy hailed the killing as a major coup in the fight against terrorism, but both he and Foreign Minister Alain Juppe warned it would not spell the demise of al-Qaeda.
German Chancellor Angela Merkel told President Obama that she was relieved about the killing of bin Laden.
