(SomaliNet) The National Union of Somali Journalists (NUSOJ) is strongly denouncing the burning of headquarters of Shacab Newspaper in Garowe of Puntland Regional State. Unknown assailants threw today petrol bombs to the headquarters of the newspaper, according to Abdi Farah Nur, the editor-in-chief of the newspaper. The flames damaged one of the printing machines of the newspaper. The Puntland police are conducting investigations, and no one was arrested for the attack. The Shacab Newspaper, which used to be published daily, was banned several times by Puntland Regional State after publishing articles critical to the Puntland leaders, and Abdi Farah Nur with other personnel were arrested quite a few times. Since then the newspaper was not published regularly. Shacab is the most independent and outspoken newspaper in Puntland. "We condemn this atrocious act and ask the authorities in Puntland to perform valid investigations and chastise people behind this" said Omar Faruk Osman, Secretary General of the National Union of Somali Journalists.
