Iran confirms it's holding another US citizen

Iran confirmed Friday for the first time that it is holding an Iranian-American peace activist, at least the fourth dual citizen it has detained in recent months, according to a semiofficial news agency. The Iranian Student News Agency said that Ali Shakeri of Lake Forest, California, was being held on security-related charges and investigated by the security department of the Teheran prosecutor's office. It provided no source for the information and calls to Iranian judicial officials were not immediately returned Friday, a weekend day in the Islamic country.
