Iran’s top diplomat said Tuesday that the deal ending the war with the United States would also require Israel to withdraw from Lebanon, raising questions about the still-unpublished agreement and whether disagreement over its terms could prolong conflict. Foreign Minister Abbas Araghchi told diplomats from other countries that Israel’s continued occupation of southern Lebanon would violate the memorandum of understanding reached between the United States and Iran, in comments aired on Iranian state television. “The end of the war in Lebanon is an inseparable part of complete end of the war,” Araghchi said.
