[MAGHAREBIA] A Tunisian judicial source on Thursday (February 28th) identified the suspected killer of opposition leader Chokri Belaid. Tunis resident Kamel Gathgathi hails from the Jendouba region, his father Taieb confirmed to AFP. Four Belaid murder suspects -- all salafists under age 35 -- were arrested earlier this week, Prime Minister-designate Ali Larayedh said on Tuesday.
