Israel has closed its embassies worldwide and is urging citizens to remain vigilant and avoid displaying Jewish or Israeli symbols in public, amid fears of Iranian retaliation following a series of Israeli strikes on Iran.

According to statements posted on embassy websites on Friday, Israel suspended consular services and urged citizens to cooperate with local authorities if threatened, without indicating how long the closures would last.

“In light of recent developments, Israeli missions around the world will be closed and consular services will not be provided,” the statement said.

Israel launched a broad preemptive attack on Iran overnight on Friday, targeting military installations and nuclear sites across the country in what officials described as an effort to neutralize an imminent nuclear threat, as nuclear negotiations between the United States and Tehran appear on the brink of collapse.

The Israeli strike killed several of Iran’s top military commanders and significantly weakened the country’s ability to retaliate, raising concerns of the risk of a broader conflict in the Middle East.

After Iran’s so-called “supreme leader,” Ayatollah Ali Khamenei warned, of “severe punishment,” the country deployed a wave of drones toward Israel, followed by two barrages of ballistic missiles, most of which were intercepted.

However, Jerusalem and many observers fear that Tehran may retaliate by targeting Jewish and Israeli interests worldwide, especially given Iran’s compromised ability to strike directly at Israel.

Iran has a long history of orchestrating violence against Jewish and Israeli targets abroad, including support for terrorism and assassination plots in the West.

Tehran has regularly called for Israel’s destruction and supported terrorist groups worldwide — including Hamas in Gaza, Hezbollah in Lebanon, and the Houthis in Yemen — by providing funding, training, and weapons.

US President Donald Trump suggested that Iran had brought the attack upon itself by rejecting Washington’s demands in nuclear negotiations to limit the country’s uranium enrichment program.

He urged Tehran to reach a nuclear deal, warning that “the next attacks already planned will be even more brutal.”

In response to Israel’s warnings of potential attacks on Jewish communities abroad, Jewish sites worldwide are strengthening their security measures.

Following a security cabinet meeting on Friday and a conversation with Israeli Prime Minister Benjamin Netanyahu, German Chancellor Friedrich Merz announced that Germany is increasing security measures for Jewish and Israeli sites.

The German leader also urged both Israel and Iran to avoid actions that could further escalate tensions, while emphasizing Israel’s right to defend its existence and the security of its citizens.

“Germany is ready to use all diplomatic means at our disposal to influence the parties to the conflict,” Merz said in a statement. “The goal must remain that Iran does not develop nuclear weapons.”

Elsewhere in Europe, Sweden has stepped up visible security around the Great Synagogue of Stockholm and other Jewish sites.

In the United States, the Secure Community Network, a leading Jewish security organization, has called on Jewish communities to “remain on heightened alert and maintain robust security measures.”

“SCN stresses that, while there is currently no credible or specific threat against the Jewish community, this development occurs amid an already intensified threat environment,” the organization wrote in a post on X.

“This environment is fueled in part by Iranian-linked actors, designated foreign terrorist organizations, violent extremists, and politically motivated groups – entities which continue to incite violence globally, including against Jewish civilians and communal facilities, often under the pretext of perceived grievances related to Israel’s war with Hamas and related military or political developments,” the statement read.

In New York City, police ramped up security at Jewish and Israeli sites amid the ongoing Iran-Israel conflict.

“The NYPD [New York Police Department] is tracking the situation in the Middle East. Out of an abundance of caution, we’re deploying additional resources to Jewish, Israeli & other sites throughout NYC,” the department posted on X. “We’re coordinating with our federal partners & we’ll continue to monitor for any potential impact to NYC.”
