Mr Meshaal this year strongly supported Mr Abbas's move in upgrading Palestinian status at the United Nations to that of a non-member "observer state".
Although a member of the UN observer mission reckons that loyalist forces include at least two combat brigades that have been held in reserve, apart from fixed-wing bombers and chemical weapons, activists report that much of the Sunni rank and file is in effect idle.
Vietnam was inducted last week as its seventh member, and Cambodia was granted official observer status and admitted into ARF, boosting that body to 19.
This campaign has been reflected at the United Nations, where the OIC's 56 members plus the Palestinian observer form one of the biggest and most influential lobbying blocs in the UN's 192-member General Assembly.
