Iran issued the Trump administration a fierce ultimatum that could collapse the tentative peace deal just a day after it was signed, Drop Site News reported Friday.

The demand was related to Lebanon, which Israel invaded in March and has since killed nearly 4,000 Lebanese and sparked a humanitarian crisis affecting millions. Included in the memorandum of understanding agreed to by Washington and Tehran was a provision that Israel terminate its military operations in Lebanon.

Israeli officials, however, have stated clearly they do not intend to cease military operations in Lebanon, and would maintain their occupation of their northern neighbor. More attacks took place Thursday night.

“Regarding Lebanon, we have warned both the mediators and the American side that if the regime fails to comply with the existing agreement, Iran will respond with substantial military measures without prior public notice,” said a senior Iranian official, speaking with Drop Site News on the condition of anonymity.

“Should the United States intervene, conditions, particularly those related to the Strait of Hormuz, could rapidly revert to a wartime environment.”
