Justin Welby: 'Islamic State is deeply evil'

The Archbishop of Canterbury, Justin Welby, has spoken out against what he called ''atrocious pressure'' on Christians and other minority communities across the Middle East.

He was speaking to the BBC during a visit to Egypt as an Islamic State video emerged, appearing to show the killing of 30 Ethiopian Christians in Libya.

''I believe Islamic State is deeply evil - even to its own supporters,'' he said.
