Israel raises alert level as U.S. weighs action in Iran unrest

Israel placed its security apparatus on high alert on January 10 after senior officials assessed the possibility of direct U.S. intervention in Iran as nationwide anti-government protests there enter their most volatile stage in years, according to Israeli sources who spoke to Reuters.

Three Israeli officials with knowledge of internal security consultations said the alert posture followed repeated public warnings from President Donald Trump that the United States is prepared to act if Iranian authorities use force against demonstrators. “The U.S. stands ready to help,” Trump said in recent remarks, after activists reported the death toll in the protests had passed 100.

According to the officials, the alert decision was taken during weekend consultations in Jerusalem as Israeli leaders evaluated the potential regional fallout if Washington moves beyond political support and considers direct involvement. The sources did not detail what Israel’s high-alert footing entails in practical terms.

The Times of Israel stated that a source present for a Saturday phone call between Prime Minister Benjamin Netanyahu and U.S. Secretary of State Marco Rubio said the two leaders discussed “the possibility of U.S. intervention in Iran.” The source did not provide further details about the operational scenarios raised during the call. A U.S. official confirmed the conversation took place but declined to disclose the topics discussed.

The protests in Iran erupted amid widespread economic frustration, fuel shortages, and renewed public anger toward security forces after a series of high-profile detentions. Crowds in major cities have defied government warnings, prompting Iranian authorities to mobilize additional paramilitary units. Activists claim more than 100 people have been killed since unrest escalated earlier this month.

For Israel, the events in Iran pose several immediate concerns. Israeli intelligence agencies have monitored Tehran’s use of its air-defense network and internal troop movements for any signs that the government may blame outside actors or attempt to widen the crisis beyond its borders. Israeli defense planning is also shaped by the memory of last year’s conflict, during which Iran launched unprecedented missile and drone attacks and Israel responded with long-range strikes against Iranian military infrastructure.

U.S. posture toward Iran has shifted sharply in recent days as Trump issued public warnings directed at Iran’s leadership. He has accused Tehran of preparing to use violence on a scale not seen since the 2019 crackdown and said Washington “will not allow mass slaughter.” Administration officials have held internal discussions about potential response options, although no details have been made public.

The reports of possible U.S. intervention discussions have drawn attention across the region as governments weigh the consequences of any American action in Iran. Gulf states, which maintain uneasy relations with Tehran, have increased intelligence coordination with U.S. agencies, according to regional diplomats who described the mood as tense but controlled.

In Israel, security officials said the current situation is being monitored continuously. The officials emphasized that the alert posture is a precaution grounded in recent history, particularly the June war that demonstrated how quickly confrontation between Iran, Israel, and the United States can escalate.

While no military actions have been announced by Washington, Israeli analysts note that any U.S. intervention—ranging from protective deployments to targeted strikes—would likely trigger rapid regional responses. Iran’s leadership has already accused the United States of orchestrating unrest, a claim Washington denies.
