Francis became pope in 2013. In recent years, the 88-year-old was forced to cancel some events, sometimes at the last minute, because of his health.

Pope Francis has died at the age of 88, the Vatican has announced.

The pontiff, who was Bishop of Rome and head of the Catholic Church, became pope in 2013 after his predecessor Benedict XVI resigned.

His death comes after a string of health worries in recent years and a lengthy stay in hospital in February and March.

The news was announced by Cardinal Kevin Farrell in a statement released by the Vatican. He said: "Dearest brothers and sisters, with deep sorrow I must announce the death of our Holy Father Francis.

"At 7.35am this morning, the Bishop of Rome, Francis, returned to the house of the Father. His entire life was dedicated to the service of the Lord and His Church.

"He taught us to live the values ​​of the Gospel with fidelity, courage and universal love, especially in favour of the poorest and most marginalised.

"With immense gratitude for his example as a true disciple of the Lord Jesus, we commend the soul of Pope Francis to the infinite merciful love of the One and Triune God."

Francis died on Monday morning, the Vatican said, just a day after greeting crowds on Easter Sunday in St Peter's Square.

The process for choosing a new pope - conclave - generally takes place between 15 and 20 days after the death of a pontiff.

In recent years, his papacy had been marked by several hospital visits and concerns about his health.

On 14 February, the Pope was admitted to hospital for bronchitis treatment.

In the days that followed, the Vatican said he had been diagnosed with bilateral pneumonia and that he had blood transfusions after tests revealed he had low levels of platelets in his blood, which is associated with anaemia.

On 22 February, it said the Pope was in a critical condition after a "prolonged respiratory crisis" that required a high flow of oxygen, and the next day the Vatican said Francis was showing an "initial, mild" kidney failure.

In the following days, thousands of faithful gathered in St Peter's Square to pray for his recovery, as others went to the Rome hospital where he was staying to leave flowers and cards.

He remained in hospital for the rest of the month, with doctors saying that his condition remained "complex".

On 6 March, his voice was heard for the first time since being admitted to hospital in an audio message, in which he thanked well-wishers, before adding: "I am with you from here."

On Sunday, he greeted crowds at the Easter Sunday Service, a day after meeting US vice president JD Vance.

His 38-day hospital stay ended on 23 March when he made his first public appearance in five weeks on a balcony at Gemelli where he smiled and gave a thumbs up to the crowds gathered outside.

He returned to the Vatican, making a surprise stop at his favourite basilica on the way home, before beginning two months of prescribed rest and recovery.

Doctors said Francis would have access to supplemental oxygen and 24-hour medical care as needed - adding that while the pneumonia infection had been successfully treated, the pontiff would continue to take oral medication for quite some time to treat the fungal infection in his lungs and continue his respiratory and physical physiotherapy.
