Leaders of six pro-US Gulf Arab states are to discuss Iran's nuclear ambitions and a stand-off between the United Nations and Syria. Foreign ministers from the Gulf Co-operation Council (GCC) will meet on Saturday before a summit that some analysts expect will call for intensified diplomacy with Iran. The GCC members are Saudi Arabia, UAE, Kuwait, Qatar, Bahrain and Oman.N Jahardhan, analyst at the Gulf Research Centre, said: "GCC countries are getting worried that things in Iran are getting out of hand. The GCC realises Iran is definitely a threat ... Things have reached a critical stage and they feel they will bear the brunt of any escalation. It is clear that there is no defined policy in Iran about what to do if it is attacked." An official associated with the two-day meeting, to be held in Abu Dhabi, capital of the UAE, said: "There is concern that Iran's nuclear programme could be weaponised. At the end of the day they [Iranians] are building a nuclear reactor across the Gulf.
