Pope Francis is still “slightly unwell” and has postponed all official audiences for Friday but is working from his residence.

Axar.az reports citing foreign media that in a statement, the Vatican did not specify what the 83-year-old pope was suffering from.

At his general audience on Wednesday he appeared to have a cold and spoke with a slightly hoarse voice, and he coughed during an afternoon Ash Wednesday service in a Rome church, his last appearance outside the Vatican.

Spokesman Matteo Bruni said the pope had said early morning Mass as customary in the chapel of the Santa Marta guest house where he lives and greeted those who attended.

“But he thought it was best to postpone today’s official audiences. The meetings scheduled to take place in Santa Marta will take place regularly,” Bruni said.

Bruni said the pope was still “slightly unwell”.
