World leaders have expressed their shock at the attacks in Paris after at least 127 people were killed in a spate of attacks.
President Michael D Higgins has spoken to the French ambassador in Dublin to express his sympathy.
In a separate statement, the President said, "On behalf of the Irish people and on my own behalf I offer deepest sympathy through President Hollande to the people of France on this dreadful loss of life and appalling injuries.
"All of our thoughts are with the people of France as events unfold".
Taosieach Enda Kenny has said: "Once again we are witnessing carnage on the streets of Paris. Again the capital is suffering at the hands of those who seek only to wreak havoc and destruction on civil society".
Speaking to Newstalk earlier, Mr Kenny said it was "the blackest of black Fridays" for France.
Tánaiste Joan Burton expressed her "disbelief and immense sorrow" following the attack.
US President Barack Obama has said the attack "is an attack on all of humanity and the universal values we share".
David Cameron has said Britain will do "whatever we can to help", while German Chancellor Angela Merkel said the attackers "hate freedom".
She expressed grief for those who have died, saying "they wanted to live the life of free people in a city that celebrates life".
Pope Francis condemned the events as "unjustifiable, inhuman acts".
Russian President Vladimir Putin said the bloodshed was "the latest testimonial to the barbaric essence of terrorism which throws down a challenge to human civilisation", and added Moscow stood ready to help "investigate the crime that took place in Paris".
United Nations Secretary General Ban Ki-moon condemned "the despicable terrorist attacks".
New Zealand Prime Minister John Key says his country "stands with France in the global fight against terror... While it is too soon to attribute blame, the attacks have targeted innocent civilians and are therefore an act of terrorism".
He also confirmed that his daughter Stephie, who is studying in Paris, is safe.
Australian Prime Minister Malcolm Turnbull said, "France, the home of freedom, has been assaulted by terrorists determined to attack and suppress freedom not just in France but throughout the world.
"But our solidarity is with them too. When the French people left the stadium after that shocking attack, they were not cowed. They sang their national anthem proudly and that is how all free people should respond to these assaults," he added.
Meanwhile landmarks across the world, including the One World Trade Center spire in New York, were lit blue, white and red to honour the dozens of people feared to have been killed in the attacks.
In Dublin, the Convention Centre was lit up in the colours of the French flag following the attacks:
