Iran said it was open to compromise in the crisis over its disputed nuclear programme as the United States and European Union pushed for Tehran to be hauled before the UN Security Council. "We have not closed the path to compromise. In principle I believe some complicated international issues can be best solved through talks," Iran's top nuclear official Ali Larijani said in an interview with the BBC. "For obtaining nuclear fuel there are many methods and formulas, and we can continue negotiations and use the different opportunities that there are in the world. I don't think the path is closed."
