Nuclear-EU-US/ 1ST LEAD: U.S. concedes on Iran: WTO and aircraft parts OK Eds: epa photos available = Washington (dpa) - In a major breakthrough on negotiations with Iran over its nuclear programme, the United States on Friday agreed to drop objections against the country's application to the World Trade Organization, and said it could also agree to the export of spare parts for aircraft. U.S. Secretary of State Condoleezza Rice in a statement emphasized that the U.S. had found a "common view" with the European Union 3 - France, Germany and Britain - on dealing with the issue. "In order to support the EU-3's diplomacy, the president has decided that the U.S. will drop its objection to Iran's application to the World Trade Organization and will consider, on a case by case basis, the licensing of spare parts for Iranian civilian aircraft, in particular from the EU to Iran," she said. --More 2253 Local Time 1953 GMT
