How many countries attended the close-door meeting held in London?

The British Foreign Office says the meeting is being called for February 2 and 3 of the 35-nation board of the International Atomic Energy Agency. The objective is for the IAEA to refer Iran to the U.N. Security Council. The Council, in turn, could impose sanctions on Iran for restarting its nuclear program at a uranium enrichment facility.The British statement comes after a close-door meeting in London of senior officials from Britain, France and Germany, along with their counterparts from the United States, Russia and China. All the countries hold permanent seats on the Security Council, except for Germany.The European countries still hold out hope for a diplomatic settlement with Iran after last week declaring negotiations had hit a dead end. British Foreign Secretary Jack Straw says me Security Council does not necessarily have to impose sanctions. "There are plenty of examples where a matter is referred to the Security Council, and the Security Council takes action, and that action is followed without the need for decisions on sanctions." Diplomats say the main focus of Monday’s meeting in London was to convince Russia and China of the need to ratchet up pressure on Iran.
