PARIS (Reuters) - Firefighter teams arrived at Notre-Dame Cathedral in less than 10 minutes after receiving the first call on Monday evening without any delays at their end, said a spokesman for the Paris Fire Department.

“We have observed no delay from the moment we were called,” spokesman Lieutenant-Colonel Gabriel Plus told reporters on Wednesday. “All over Paris, firefighters arrive anywhere in ten minutes, it was the case that evening,” he said.

Gabriel Plus declined to comment on whether the fire alarm mechanisms worked normally, adding that investigators were looking into that.

He reiterated that all the paintings remaining in Notre-Dame’s chapels were in good condition.
