The authorities in Nagorno-Karabakh have again refused to grant citizenship to a bitter critic of Armenias government who played a prominent role in the 1991-1994 war with Azerbaijan, it emerged on Monday. <br /><br />Zhirayr Sefilian, a Lebanese citizen of Armenian descent, commanded one of the Karabakh Armenian units that fought Azerbaijani forces and retired from the Karabakh military in the rank of lieutenant-colonel in the late 1990s. He has since been based in Yerevan, cooperating with local opposition leaders and actively campaigning against any territorial concessions to Azerbaijan.
