Just 72 hours after a bitter confrontation at the OPEC meeting in Vienna on 18 September which resulted in Iran, Libya and Algeria splitting away from the other ten members, Iran announced full mobilisation of its armed forces. At the meeting where Iran's enmity towards her neighbour Iraq and to a lesser extent Saudi Arabia was not muted, Iran wrecked OPEC's chances of a united pricing policy by pushing up her oil prices to $35.37 per barrel. To add pressure, say several sources, Iran stepped up its offensive against Iraq over their 1975 border treaty dispute.
