Pope Francis welcomed by huge crowds for Philadelphia mass

Pope Francis has joined hundreds of thousands of the faithful for the last and biggest event of his six-day US visit – a mass on Philadelphia’s grandest boulevard.

Riding through the streets in his open-sided pope-mobile, the pontiff waved to cheering, sceaming, singing, flag-waving crowds as he made his way up the Benjamin Franklin Parkway and reached the altar at the foot of the broad steps of the Philadelphia Museum of Art.
