Almost twoweeks of negotiations in Vienna between Iran and the P5+1 group- the U.S., Russia, China, Britain and France plus Germany -ended on Friday with no final agreement between the two sides,and with the deadline being pushed back to Nov. 24. The IAEAsaid Iran's actions were a tangible sign of the country'swillingness to respect last November's commitment. The factthat Iran still has 19,000 uranium refining centrifuges that itwishes to keep intact remains a thorny question. . .
