Palestinian leader Yasser Arafat urged Iran and Iraq to end their 18 -month-old war at a meeting of foreign ministers of the nonaligned movement in Kuwait, 50 miles from the battlefront.
''It is necessary to halt this war immediately . . . and unify our efforts to confront the enemy, international imperialism and its ally Zionism,'' Mr. Arafat said.
Mr. Arafat, who seeks a diplomatic boost for the Palestine Liberation Organization as a peacemaker, made his appeal before the 96-member nonaligned movement, which met also to consider ways of helping the Palestinian cause against what ministers called continued Israeli aggression in occupied Arab territories.
Mr. Arafat attacked the United States for ''unlimited'' support of Israel despite the annexation of the occupied Golan Heights and the firing of three Palestinian mayors in the occupied West Bank.
The Iranian delegation later walked out of the conference when Ismat Kittani of Iraq addressed the ministers in his capacity as president of the United Nations General Assembly.
