The ruling military council of Mauritania has freed 32 political detainees after a comprehensive amnesty decree.
Mauritania's new military government has told the country's main political parties that elections would follow a constitutional referendum to be held within a year and that none of its members would stand.
Soldiers have surrounded Mauritania's state radio and blocked off streets in the capital while President Maaouya Ould Sid'Ahmed Taya was out of the country, in what a diplomat said could be a coup attempt.
