KUWAIT, AUG. 12 -- Iran alluded to the 1983 truck-bomb attacks against multinational forces in Lebanon in a warning to France and Britain today that their decision to dispatch mine sweepers to the area would only increase tensions.

The Iranian warning, broadcast on Tehran radio, came as another mine was found in waters outside the Persian Gulf. Oman stepped up mine-hunting operations around the normally crowded anchorage off the port of Fujayrah, on the Gulf of Oman, where the U.S.-operated supertanker Texaco Caribbean was holed by a mine Monday.

Tehran radio said Iran had asked leaders of the United Arab Emirates for permission to conduct mine-sweeping operations in the emirates' territorial waters, Agence France-Presse reported.

Omani mine sweepers discovered four mines off Fujayrah yesterday and a fifth today -- all within the offshore anchorage used by dozens of tankers and freighters to load fuel and supplies before or after making trips to the Persian Gulf.

"Mines appear to be turning up in clusters" in an area nine miles northeast of Fujayrah, a local shipping source reported.

The discovery of the first mines on Monday, in what had previously been thought to be safe waters, prompted both Britain and France to reverse themselves yesterday and agree to dispatch mine sweepers to help safeguard their shipping in the area.

Meanwhile, shipping sources here said today that the U.S. Navy used a chartered, Liberian-registered freighter as a makeshift mine sweeper to lead the latest convoy through the most dangerous waters to Kuwait. The ship was packed with sonar equipment and led the convoy -- made up of four U.S. Navy escorts and three reflagged Kuwaiti vessels -- single file into Kuwaiti territorial waters.

The United States was caught off guard on July 24 when the reflagged Kuwaiti supertanker Bridgeton was damaged by a mine during the first U.S. Navy-escorted convoy to Kuwait. Washington quickly asked its European allies to provide mine-sweeping assistance, but France, Britain, West Germany and the Netherlands -- all nations with large mine-sweeping fleets -- declined.

The change of mind by Britain and France, however, has angered the Iranians, who in radio commentaries today insisted that the security of the Persian Gulf should be left to the nations of the gulf, not outsiders.

The United States has said that it is reasonably certain that the mines found n Persian Gulf shipping lanes were laid by Iran. Although the mines found off Fujayrah are of similar design, it has yet to be determined who placed them.

Iran has blamed the United States, its allies or Iraq for laying the mines off Fujayrah. The Texaco Carribean was loaded with Iranian crude oil when it struck the mine on Monday.

"If England and France want to stand back-to-back with the American forces to implement the aggressive policies of the Reagan administration," Tehran radio said today, "we are ready to repeat the events of Lebanon, which resulted in their flight."

The comment was an apparent reference to the multinational force sent to Beirut by the United States, France, Italy and Britain in 1982 after the Israeli invasion of Lebanon.

The force, which withdrew in early 1984, was devastated by two simultaneous truck-bomb attacks in October 1983 that leveled the barracks of U.S. Marines and French troops and killed about 300 servicemen of the two countries. U.S. intelligence indicated that the attacks were orchestrated by Iran, possibly with Syrian assistance.

Although Britain and France both said they were sending mine sweepers to the area to protect only their own shipping in the Persian Gulf, Iranian Prime Minister Mir Hossein Mousavi today said they were coming to reinforce the U.S. naval presence in the gulf.

"France and England have backed America in the various aggressions it has committed in different parts of the world, and now we see the same scenario again," Mousavi said in an interview broadcast on Tehran radio.

{The Reagan administration Wednesday accused Iran of trying to obstruct and delay a United Nations effort to impose a cease-fire in the gulf war and said the world body should move quickly toward sanctions against Tehran unless it changed its "negative" attitude, The Associated Press reported.}

Tehran's anger stems from the U.S. decision last month to raise the Stars and Stripes over 11 Kuwaiti-owned tankers so they could receive U.S. Navy protection. So far, the Navy has escorted two convoys of reflagged Kuwaiti ships, the second of which reached here last night.

Kuwait requested protection for its shipping because of persistent threats by Iranian Revoutionary Guards to attack ships suspected of providing logistical support to Iraq. Iran has criticized Kuwaiti support for Iraq in the seven-year-old Persian Gulf war.

The nine-ship U.S. Middle East Task Force operating in the gulf was caught unprepared for mines when it brought in its first convoy last month and the Bridgeton was damaged by a mine.

Eight mine-hunting Sea Stallion helicopters were airlifted to U.S. naval facilities on the Indian Ocean island of Diego Garcia earlier this month and loaded onto the helicopter carrier USS Guadalcanal.

{After its departure was delayed by an electrical problem, the Guadalcanal left Diego Garcia Wednesday and was expected to reach the Persian Gulf in about a week, Reuter reported.

{It also reported from Fujayrah that the United Arab Emirates Coast Guard had lost track of one of the mines it detected on Tuesday and failed to detonate another mine after pounding it with gunfire.

{"We are missing the mine that was here this morning," a Coast Guard officer told reporters flying over the Gulf of Oman in a helicopter. "If you can locate it, please tell us."}

In other developments, Iran reported today that its forces had killed or wounded 1,000 Iraqi troops on the northern war front in Iraqi Kurdistan. Iranian military communiques also reported extensive artillery shelling of industrial targets in the southern Iraqi port city of Basra and the nearby naval base of Umm Qasr.
