The Imam of Peace
Back in the 1960s, a young English hippy arrived in Kabul, looking for a good time and cheap drugs. Instead he found there a tribal culture that entranced him.
Forty years on, he's still there - now a Muslim, a trained Imam, a journalist, a Pashtu speaker and a man with a mission.
His name is John Mohammed Butt and he's made it his life's work to spread a message of peace and tolerance in the tribal regions that straddle Afghanistan and Pakistan.
But as reporter Nadene Ghouri discovers in this week's Assignment, that message has made him a target for militants.
