An Irish priest based in Paris has compared the "resilience" of the French to those who lived through the Troubles in the North.
Fr Aidan Troy, who famously led a group of Catholic schoolgirls through violent Loyalist protests in Belfast in 2001, said attacks like that on Thursday in the French Capital had become a familiar occurrence.
"I left Belfast over eight years ago having lived among brave and resilient people of different outlooks and aspirations whom I admire and will never forget," he said.
"Here in Paris, the people will not give up living and working in as normal a way as possible."
Fr Troy, of St Joseph's Catholic Church, said there was a sense of uncertainty and fear in the air.
"In the streets people stood in small groups trying to piece together yet another attack," he said.
"Tired children cried - all they wanted was to get to bed.
"Armed police and soldiers were to be seen in the nearby metro station and at every street corner.
"This has become a familiar sight."
Fr Troy added that it was business as usual in Paris yesterday.
"I saw a city rally and begin a new day with courage and resolve," he said.
"Restaurants opened, shops began to sell. I cycled to a school for an Easter celebration at a nearby church.
"Over 300 children, of all religions and none, took part. They were supported by parents and teachers. Police ensured our safety."
