Iran again warned Western nations yesterday they risked sparking an oil crisis if economic sanctions were slapped on Tehran over its disputed nuclear activities. “In case of sanctions, other countries will suffer as well Iran, but the damage will be more for them, because one of the consequences will be the unleashing of a crisis in the oil sector and particularly a price hike,” Oil Minister Davoud Danesh-Jafari said, according to the official news agency IRNA.However the minister did not raise the possibility of any suspension or restriction of Iranian oil supplies in case of sanctions. Iran, the number two oil exporter in OPEC, risks being referred to the UN Security Council over what the West suspects is a covert nuclear weapons drive. The Islamic republic, OPEC’s number-two producer, insists it only want nuclear technology to generate electricity. “The conditions are not right for a Security Council referral because Iran has done nothing illegal,” Danesh-Jafari said.
