The funeral of Pope Francis, who died on Easter Monday aged 88, is taking place in the Vatican.
Dozens of leaders and dignitaries - including Donald Trump, Volodymyr Zelensky, and Prince William - have joined 40,000 mourners in St Peter's Square.
Trump, Prince William, and other leaders paid their respects to Pope Francis' coffin inside the basilica before the service began.
Trump and Zelensky met before the funeral, Zelensky's spokesman says, as negotiations to end the war in Ukraine continue.
Ukraine's President Zelensky appeared in St Peter's Square, applause could be heard from the crowds (there are several large screens showing proceedings in the square).
About 140,000 people are now gathering in St Peter's Square and the nearby streets for Pope Francis's funeral, Italian police report.
That includes 40,000 people in St Peter's Square itself, which is almost at capacity.
This section asks the faithful to listen and reflect on readings from the Bible.
Pope Francis's funeral mass includes a reading from the Acts of the Apostles (read by Kielce Gussie, a journalist from Vatican News) followed by a second reading from the Letter of Saint Paul to the Philippians.
In between the two readings will be a responsorial Psalm.
Pope Francis's funeral service this morning is being led by the dean of the College of Cardinals, Giovanni Battista Re.
The 91-year-old Italian was ordained for the Diocese of Brescia in 1957. In 2001, Pope John Paul II proclaimed him as a cardinal.
He was elected as dean of the College of Cardinals in 2020, and Pope Francis extended his term in February this year.
He participated in the conclave of April 2005, which elected Pope Benedict XVI and in the conclave of March 2013, which elected Pope Francis.
