Pope Francis questions Donald Trump's Christianity

The Pope has questioned US Republican presidential candidate Donald Trump's Christianity over his call to build a border wall with Mexico.
Pope Francis said "a person who thinks only about building walls... and not of building bridges, is not Christian".
The New York businessman supports deporting nearly 11 million undocumented immigrants.
Calling himself a "proud Christian", Mr Trump blamed Mexico for the Pope's remarks, calling them "disgraceful".
Mr Trump has alleged that Mexico sends "rapists" and criminals to the US.
Pope Francis made the comments at the end of trip to Mexico.
"A person who thinks only about building walls, wherever they may be, and not of building bridges, is not Christian. This is not the gospel," he said.
