The Guardian reports:
Nabbous was apparently shot dead by Gaddafi forces in Benghazi on Saturday. Known as "Mo", Nabbous set up Libya al-Hurra TV, which broadcast raw feeds and commentary from Benghazi, on Livestream. ... His death comes after the shooting of Al-Jazeera cameraman Ali Hassan Al Jaber in an ambush outside Benghazi earlier this week.
