The media advocacy group Reporters Without
Borders (RWB) has joined calls for Iranian authorities to reveal the whereabouts of
two opposition leaders, RFE's Radio Farda reports.
Supporters of Mir Hossein Musavi and Mehdi Karrubi say they and their wives
were taken from their homes in recent days and transferred to a jail in the
capital, Tehran.
Iranian authorities have denied this, saying the two couples are still in their
homes.
Western officials have condemned the reported detention of Musavi and Karrubi
and called for their release.
Reza Moini, head of the Iranian section of RWB, told
Radio Farda that the secretive arrest of political prisoners is against
international law.
"We have questioned the Iranian authorities regarding this matter," he said,
"and have demanded the immediate disclosure of the arrest situation and
location of these figures as per international law and the Iranian Constitution
suggesting that the charge, along with the reason [for the charge], should be
announced upon every arrest."
Moini said his group has kept track of the many threats it says have been made
against Iranian intellectuals both inside and outside Iran in recent years.
"We have asked for international assistance in this matter, and have demanded
the safety of Iranian journalists both inside and outside the country," he
added.
