Iran could make European countries suffer by cutting off energy supplies and can target any adversary with its missiles, a senior Iranian military official said Sunday. Iran is locked in dispute with the United States and its allies over its nuclear energy programme which Western countries fear is aimed at allowing Iran the chance to develop nuclear weapons. Tehran says it is only interested in electricity. The International Atomic Energy Agency's (IAEA) governing board meets in Vienna next week to discuss Iran while world powers are deliberating new sanctions on Iran at the level of the UN Security Council. Iran is one of the world's biggest oil and gas exporters but its economy is suffering amid the global financial crisis and international ostracism over the nuclear dispute.
