Pope Francis in Middle East: Tight security around pontiff

Huge crowds lined the streets of Jerusalem's Old City on Sunday to greet Pope Francis, who is on a three-day tour of the Middle East.

More than 8,000 local Christians also attended an open-air mass by Bethlehem's Church of the Nativity - but some people were left frustrated by the level of security surrounding the pontiff.
