Ayatollah Ali Khamenei, Iran's supreme leader, said on Sunday that energy flows in the region would be endangered if the United States made a "wrong move" towards Iran. His remarks, which are likely to unsettle wary oil markets, come days before EU foreign policy chief Javier Solana is due to deliver a package of incentives agreed by six world powers and designed to persuade Iran to abandon plans to make nuclear fuel. "If the United States make a wrong move regarding Iran, definitely the energy flow in this region will be seriously endangered," Khamenei, who has the last word in all matters of state, said in a speech which discussed the dispute. President Mahmoud Ahmadinejad said on Saturday Iran would consider the proposals from the United States, Russia, China, France, Germany and Britain but also insisted that the crux of the package was unacceptable.
