A conductor has twice stopped an opera in Cardiff after mobile phones rang in the audience.
Carlo Rizzi was conducting Welsh National Opera's new production of Verdi's Les Vêpres Sicilienes, at Donald Gordon Theatre at the Wales Millennium Centre on Saturday night.
Audience members said Rizzi twice stopped and spoke to the audience about the distraction it caused.
Verdi's opera is based around true events in Sicily in 1282.
David Jackson, a BBC employee who was in the audience, said Rizzi was applauded after bemoaning the interruption caused by mobile phones.
He said: "I spoke to Carlo afterwards and congratulated him on the performance, but also on tackling the phone miscreants.
"He got a warm round of applause after he stopped and ticked off the audience member. Both incidents were right at the beginning of the show and all was well after that."
The opera is sung by WNO in French in its new production directed by Sir David Pountney.
Another audience member confirmed the two instances of disruption caused by mobile phones.
It is not the first time a mobile phone has drawn irritation during a high-profile live performance, with the devices falling foul of numerous artists in the past.
Pianist Krystian Zimerman stormed out of a concert in 2013 because a fan was filming with his phone.
Last year, singer Madonna said she would ban mobile phones from future gigs.
Jackson said his enjoyment of the opera in Cardiff was not affected by the interruptions.
"It was a wonderful performance of a comparatively rarely done piece of Verdi - the mobile phone business didn't detract," he said.
WNO confirmed there were "short pauses" and that Rizzi addressed the audience following the second interruption.
