The kidnappers of an Italian journalist in Afghanistan have offered to free him in exchange for a Christian convert who fled the country, an aid agency says.
Photojournalist Gabriele Torsello was seized last week while travelling on a bus in southern Afghanistan.

Mr Rahman had escaped a possible death sentence for becoming a Christian.
