Pope arrives at envoy's residence to spend night

Pope Francis has arrived at the Vatican ambassador's residence in Mexico City where he will sleep during his five-day visit to Mexico.

He drove from the airport to the capital's south side in an open-air popemobile waving to the crowds lining the route. As planned, he did not make any public comments.

The motorcade paused at one point when a man appeared to get past security barriers and run toward the popemobile. The man was intercepted by security officials and the convoy moved on.

Security is tight outside the papal nuncio's residence. People stood outside huddled against the cold, some covered with blankets.
