Thousands flock to Vatican as teenager made first millennial saint

The first millennial saint has been canonised by Pope Leo on Sunday, with thousands attending the ceremony in Rome.

Carlo Acutis, a London-born Italian boy, died of leukaemia in 2006, aged 15.

He has been labelled "the patron saint of the internet" for his work recording miracles online, and running websites for Catholic organisations.

A picture of Carlo Acutis hung in Saint Peter's Square as the Pope praised the young man's faith.

A second man was also canonised, Pier Giorgio Frassati, an Italian mountaineering enthusiast who served the poor and sick, and died in 1925.
