Amid turmoil and uncertainty in Libya, reliable information is at a premium and the media is an important weapon.

Colonel Gaddafi's regime still controls the state television and radio stations broadcasting from Tripoli, but in Benghazi - a rebel stronghold - a new radio station has begun to broadcast.

It is called The Voice of Free Libya.

Ahmed Ali - his name changed to protect his identity - is one of the people who started it.

Ahmed worked for many years as a television and radio engineer in Benghazi.

Most of his career was spent under tight censorship, with technicians and producers having no option but to transmit the messages of the Gaddafi regime.

At times this included filming and broadcasting the execution of political dissidents.

Ahmed describes the emotional moment when he and his colleagues were able to broadcast freely for the first time in 42 years.

Speaking to Outlook's Matthew Bannister, he began by explaining that having trained as a broadcast engineer elsewhere, he found returning to Libya a shock.
