Iran Feature: The Fear in the Corridors of Evin Prison (Theodoulou)
From grim experience, Maziar Bahari knows the fear that is probably gripping eight Iranian journalists who were arrested late last month and taken to Tehran's notorious Evin prison.
Mr Bahari was among the approximately 100 journalists detained in June 2009 during the tumult following president Mahmoud Ahmadinejad's disputed re-election.
The latest crackdown on reporters affiliated with reformist news outlets appears to be aimed at muzzling dissenting or independent voices, and suggests that as Iran gears up for its next presidential election in June, the regime's fears of unrest are escalating.
"My guess is they're all in solitary confinement," said Mr Bahari, an Iranian-Canadian journalist and filmmaker who spent 118 days in Evin, all but 11 of them alone in a small cell.
