VATICAN CITY — Pope Francis has canceled a planned July trip to Africa on doctors' orders because of ongoing knee problems.

The Vatican said the July 2-7 trip to Congo and South Sudan would be rescheduled “to a later date to be determined.”

Francis has used a wheelchair for about a month due to strained ligaments in his right knee that have made walking and standing difficult.

As recently as this week, however, plans were proceeding for the trip to the two African countries.

But questions have swirled for months about the 88-year-old’s ability to manage the taxing journey.

Francis also has a July 24-30 visit to Canada planned. A Vatican statement said nothing about that trip.

A celebration over a newly constructed bridge in the Democratic Republic of the Congo went awry as the bridge wasn't quite ready for the stress test that revelers put on it during the ceremony.

As people stood on the bridge during a ribbon cutting ceremony, the bridge gave out and collapsed.

Video showed people grabbing on to each other as it fell.

The bridge appeared fairly small and over a gap in the Earth that wasn't too high, so no one was seriously hurt in the incident, Now This News reported.
