An Iraqi Shi'ite group says kidnappers have freed an Iraqi interpreter taken hostage with a British journalist in southern Iraq recently.

The office of radical Shi'ite cleric Moqtada al-Sadr says the interpreter was released Wednesday in the southern city of Basra. Gunmen had seized the interpreter and his British colleague from a Basra hotel on Sunday.

Al-Sadr's office in Basra said earlier that it had reached a deal with the kidnappers for the release of both hostages, who work for the U.S. television network CBS. It was not clear when the British journalist would be freed.
