Philadelphia prepares for the Pope

Next week Pope Francis arrives in the United Sates to begin an historic six-day visit.

In Washington DC he will hold the first-ever canonisation mass on US soil and then give the first address to Congress by a pope. In New York City he will attend the United Nations General Assembly to mark its 70th anniversary.

The final leg of Pope Francis' US tour is Philadelphia where the pontiff will preside over the Vatican's World Meeting of Families. It's being billed as one of the largest events in the City of Brotherly Love in modern times and could attract up to a million and half people.

From Philadelphia, Michael Maher reports.
