Report: Israel Warns U.S. Iran's Chemical Weapons Plans Are Nearer Threat Than Nuclear Program

Update, Nov. 4, 7 AM CT

A senior Israeli defense official told Ynet on Wednesday that Iran has "no chemical capability that poses a threat to Israel." That contrasts with the Times' account of Israel's warning to the U.S.

The New York Times says CENTCOM has a strike plan that could be used as early as Nov. 4, but President Trump has not approved it and diplomacy is continuing (NYT via Boston Globe). Home Front Command is holding drills across Israel this week; according to the Times, chemical-weapons preparation is not a major part of them.

Update, Nov. 3, 5 PM CT

Hospitals (Reported by Sky News Arabia; awaiting wider confirmation). Sky News Arabia, citing its correspondent, reports that parking lots at most major Israeli hospitals are being cleared and turned into emergency wards. In a separate report, it said parking lots at Jerusalem hospitals are being converted and equipped as shelters. An X summary of the report says some Jerusalem hospitals are moving wards underground. According to Türkiye Today, which relayed the Sky News Arabia reports, they did not say which hospitals were affected or who ordered the work (see also the X summary). We did not find the Sky News Arabia article itself, and no Israeli or wire outlet has confirmed the hospital measures. An earlier AFNS research check at 3 PM CT had flagged a similar hospital claim as unverified.

Northern shelters. Karmiel's municipality says the city's public shelters are open and ready for use. Mayor Moshe Koninsky called it early preparation and urged residents to keep their routines and follow Home Front Command instructions. The city says the shelters have been available for about two weeks (Channel 14, VINnews). VINnews says reports indicate shelters were also opened or made available in Kiryat Shmona and Safed.

Precautions only. Officials say these are precautionary steps and that nothing has changed on the ground. Karmiel officials said "there is no change in the current situation" (VINnews), and the public is being told to follow Home Front Command guidance. No new Home Front Command directive has been reported.

The earlier 3 PM CT report follows.

Status: Reported by the New York Times; officials divided. This story rests on the Times' reporting, which cites unnamed U.S. and regional officials, along with the Jerusalem Post, Times of Israel and Ynet accounts of it. AFNS has not seen the underlying intelligence. The Israeli military declined to comment, according to the Times.

What the Times reports

Israel has shared intelligence with the United States asserting that Iran is considering the use of chemical weapons against its adversaries, the New York Times reports, citing U.S. and regional officials (NYT). The report first circulated widely on X via Polymarket.

In conversations with U.S. spy agencies and other officials over the past two weeks, Israeli officials have portrayed the chemical weapons threat as more urgent than Iran's ambitions to develop a nuclear weapon, according to the Times. Israeli intelligence told U.S. counterparts it believes Iran is moving rapidly to develop the technology to put such weapons on a missile or smuggle them into Israel or another country, according to American officials cited by the Times.

Officials divided

The Times reports that the intelligence was met with alarm by some American officials and deep skepticism by others.

• Skeptics: some U.S. officials see the intelligence as part of a pressure campaign by Prime Minister Benjamin Netanyahu's government to persuade the Trump administration to return to major combat operations against Iran.
• Gulf officials: Israel shared some of the information with Gulf countries. Several Gulf officials doubted Iran was developing such plans and believe Israel is trying to push the U.S. and its partners back to a more intense phase of the war. A regional official said Israel had not shared supporting evidence (as relayed by the Jerusalem Post and Ynet).
• Those taking it seriously: other officials say the threat should be taken seriously given recent warnings about Iranian preparations to attack American interests.

Background, per the Times: Iran acknowledged in 2003 that it developed chemical capabilities during the Iran-Iraq war and said it later dismantled them. U.S. annual intelligence assessments say Iran "likely aims" to continue chemical weapons research and development.

The Times also reports that Israel's Home Front Command drills this week are not focusing on chemical weapons preparation (Times of Israel).

CENTCOM strike options (per the NYT)

The New York Times now reports that CENTCOM has a strike plan that could be used as early as Nov. 4, but that President Trump has not approved it and diplomacy continues (as published by the Boston Globe). Earlier, an X story summary said CENTCOM has strike options ready as early as Nov. 4 (X). The Jerusalem Post, in its account of the Times report, says senior U.S. officials described a CENTCOM plan that could be carried out as early as Wednesday, Nov. 4. Trump has not approved the plan, per the NYT.
