Al Jazeera says Libya authorities free correspondent

CAIRO - Libyan authorities have released Al Jazeera's Mauritanian correspondent, one of four staff who were detained by leader Muammar Gaddafi's forces, the Qatar-based news channel said on its website on Monday.
"Libyan authorities released Al Jazeera correspondent Ahmad Vall Ould Eddin after he was held in custody for more than a month," the channel said. "This came in conjunction with a visit by an African delegation to Tripoli."
The reporting team of two correspondents and two cameramen was arrested near Zintan in northwest Libya and held in the capital Tripoli for three weeks, Al Jazeera said.
It said they were released but then re-arrested hours later on March 31.
