Pope laid to rest

Hundreds of thousands of mourners joined world leaders, including US President Donald Trump, to bid farewell on Saturday to Pope Francis, a champion of the poor who strived to forge a more compassionate Catholic church.

The Vatican said 400,000 people packed St Peter's Square and lined the streets of Rome for the funeral of the first Latin American leader of the world's 1.4 billion Catholics.

After a solemn funeral, the Argentine pontiff's plain wooden coffin -- a testament to a life of humility -- was driven slowly to Rome's Santa Maria Maggiore church, where he was interred in a private ceremony.

Cardinals marked his coffin with red wax seals before it was lowered into a tomb set inside an alcove, according to images released by the Vatican.

Guatemalan Maria Vicente, 52, holding a rosary, cried as she watched the coffin being carried into Santa Maria Maggiore.

"It made me very sad. It's touching that he left us like that," she said.

The marble tomb is inscribed with just one word: "Franciscus".

Trump was among more than 50 heads of state at the funeral. He met several world leaders in a corner of St Peter's Basilica before, notably Ukraine's President Volodymyr Zelensky, in their first face-to-face meeting since their Oval Office clash in February.

Francis, who died on Monday aged 88, was "a pope among the people, with an open heart", who strove for a more compassionate, open-minded Catholic Church, said Cardinal Giovanni Battista Re who led the service.
