AMMAN, JORDAN, SEPT. 29 -- Iraqi Foreign Minister Tariq Aziz arrived here unexpectedly today with a message from Iraqi President Saddam Hussein thought to be linked to Arab requests for his written commitment that Iraqi forces will eventually pull out of Kuwait.

Jordanian officials refused to disclose the contents of Saddam's message, saying simply that it was "related to recent developments in the {Persian} Gulf crisis." Aziz met with King Hussein for several hours and lunched with him before flying back to Baghdad.

"The situation is extremely delicate now, but Jordan has not given up on efforts to defuse the tension," one official said.

A meeting including Jordan's Hussein, King Hassan of Morocco and Algerian President Chadli Bendjedid 10 days ago produced no major breakthroughs but concluded with the dispatch of a letter to Saddam. The letter signed by all three leaders expressed their willingness to pursue peace initiatives in return for a "written commitment" or "sign" from the Iraqi leader that he would be ready to pull out of Kuwait, which Saddam's troops invaded Aug. 2 and subsequently annexed.

Iraq's ruling Revolutionary Command Council said last week that its annexation of Kuwait was irreversible, but the appearance here by Aziz gave rise to speculation that Saddam may be groping for diplomatic channels to circumvent a tightening U.N. economic embargo against his nation.

Jordan's precarious position as one of the states hit hardest by the U.N. embargo against Baghdad -- as well as strong popular sentiment within the country against the U.S.-led military buildup in the Middle East and in favor of Saddam's defiance of the West and its Arab allies -- prompted Hussein to defer by 48 days the convening of Jordan's fledgling legislature. Elected late last year, it is predominantly pro-Iraqi and Hussein's move could be aimed at avoiding pressures on the government for alignment with Baghdad.

News services reported:

The first of thousands of British ground troops and military hardware were on their way to Saudi Arabia Saturday to join U.S. and other forces facing the Iraqi army.

Initial estimates put the number of troops of the 7th Armored Brigade and support units being sent to the Persian Gulf at between 6,000 and 8,000. But the Times of London said the number could reach 9,000.

In Brussels, Belgian Foreign Minister Mark Eyskens said most members of the European Community plan to close their embassies in Kuwait next week because diplomats are running out of water and food, according to Reuter. Saddam has ordered all Western diplomats in Kuwait to move to Baghdad.

But in London, a Foreign Office spokesman said Britain planned to keep its embassy in Kuwait open "as long as physically and practically possible," and a Dutch Foreign Ministry spokeswoman said the Netherlands' embassy remained open.

A Kuwaiti businessman told the Associated Press Saturday that he saw Iraqi soldiers summarily execute eight men accused of resistance activities in Kuwait.
