PRICE TALKS BY OPEC POSTPONED
The 13 OPEC oil ministers who gathered here to seek an accord on lowering oil prices postponed their first full meeting until Tuesday - and perhaps later - after Iran insisted it would never agree to a cut in OPEC's official prices. Instead of the expected meeting, the day and evening were spent in a series of negotiations among small groups within the Organization of Petroleum Exporting Countries. The setback tempered the optimism that had prevailed among the eight ministers who had called for a full meeting. This group, led by Saudi Arabia and Venezuela, has held informal talks over the past 10 days; by last Thursday, they seemed to be making headway.
