Four journalists working for Al-Jazeera, including a Norwegian and a Briton, are being held in Tripoli after being arrested in Libya's west, the Qatar-based satellite channel said late Saturday.
Al-Jazeera said Lotfi al-Messaoudi, a Tunisian, Ahmed Vall Ould Addin, a Mauritanian, Ammar al-Hamdan, a Norwegian cameraman, and British national Kamel Atalua were arrested while "carrying out their duties" in western Libya.
A statement on the channel's website said that the Libyan authorities "will be held accountable for the safety, security and well-being of the team."
It added that "regional parties" were combining their efforts in a bid to secure the journalists' release, but did not elaborate.
In Oslo, a spokesman for the foreign ministry, Frode Andersen, said they had been informed by Al-Jazeera that a journalist with Norwegian nationality had been arrested by forces loyal to Libyan strongman Moamer Kadhafi.
