Pope Francis took a phone call during his weekly General Audience.
It happened near the end of the audience, when the catechesis was being summarized in English.
The Pope has taken calls during other public appearances. For example, in 2021, he interrupted his meeting with the staff of the Secretariat of State to answer a call.
The Vatican has not given details about this call that compelled the Pope to answer during a public event.
