Firefighters Rescue Pope Francis at The Vatican (Video)
"I have to apologize for being late," a smiling Pope said at the start of the Angelus address.
He then asked the crowd for a round of applause for the firefighters.
Addressing the crowd, the Pope said there had been a "drop in voltage and the elevator stopped".
"Thank goodness, the firefighters arrived, and I thank them so much, and after 25 minutes of work they managed to get it started again," he said.
