In a rare interview with a foreign broadcaster, opposition leader Mehdi Karoubi tells the BBC that Ahmadi's days are numbered:
"The government's response, the crackdown, has not calmed things down at all. In fact, it's just made the chanting louder. It's just increased the people's demands." He stood by his allegations that opposition activists have been raped in detention - a charge vehemently denied by authorities. He said he was not afraid of being prosecuted over the claims as threatened by several government officials.
