One Irish citizen has been injured in the Paris terror attacks.
The Department of Foreign Affairs in Dublin said there was no indication that anyone else from Ireland had been caught up in the violence.
As the Irish Embassy in France provided consular assistance to the injured citizen, the Irish president joined political and church leaders across the island in expressing sympathy and solidarity to the people of France.
President Michael D Higgins 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.”
Taoiseach Enda Kenny said his country stood with the French.
“As ever we stand as one with them and will never bend to the evil of terrorism,” he said.
In Northern Ireland, First Minister Peter Robinson and Deputy First Minister Martin McGuinness said they were shocked and saddened.
“Our thoughts, prayers and sympathies are with the French people and we stand shoulder to shoulder with President Hollande and France following these savage, barbaric and cowardly terrorist attacks in Paris,” they said in a joint statement.
Belfast City Hall will be lit in the colours of the French flag on Saturday night.
The leader of the Catholic Church in Ireland Archbishop Eamon Martin asked for prayers for those who died and were injured.
“Our thoughts and prayers are with the people of Paris today and we express our solidarity with the French community living here in Ireland,” he said.
“I ask everyone to remember, at Mass and in prayer this weekend, all those who have died and their families. We also pray for those injured and all who are caring for them.
“These horrific events challenge us to pray and work even more earnestly for an end to the evil of terrorism everywhere. Each of us by our own thoughts, words and actions is called to spread mercy, love and peace so that the horrors of evil shall never conquer the world.”
Ireland’s consular response centre is open for any families who have concerns about loved ones in France to contact officials on +353 (0) 1 418 0200 or firstname.lastname@example.org.
Foreign Affairs Minister Charlie Flanagan said officials in France and Dublin worked through the night to monitor the situation and provide consular assistance.
Mr Flanagan added: “Our advice remains that Irish citizens in Paris should exercise caution, stay indoors and continue to follow the instructions of the local authorities.
“Any citizens intending to travel should check with their airline or tour operator for information - the airports are operational but citizens should expect additional security and travel disruptions.
“Citizens should continue to monitor the Department of Foreign Affairs and Trade’s twitter feed @dfatravel and our travel advice at www.dfa.ie which will be updated in line with developments.”
