burial

After the service, Francis's body — dressed in a red chasuble and a damask and golden papal mitre — will be transported to the basilica of Santa Maria Maggiore in Rome for burial.

"It's darker and seems more organic, so potentially some time had elapsed between the burial of the adults and the burial of these two children - it's more mystery."

The coffins used for previous papal burials consisted of three nesting coffins made of cypress, lead and oak - but Pope Francis asked to be buried in a simple wooden casket.

The pontiff's body will then be taken inside the church before being transported to St Mary Major basilica in Rome for burial.

A funeral and burial are expected in four to six days, per church rules.
