US on alert over alleged advanced-stage Iranian plots against Americans abroad

United States intelligence agencies have warned that Iranian plots to target US personnel overseas have reached advanced stages, according to a memo cited by officials. The warning has prompted Washington to place staff on high alert across parts of the Middle East and to reduce its diplomatic presence in the region. The development comes amid already elevated tensions between the United States and Iran.

The memo was sent by Director of National Intelligence Jay Clayton to Secretary of State Marco Rubio, according to the supplied report. It says US agencies have received intelligence indicating that Iran has substantially increased efforts to target US personnel abroad. The assessment says lethal plots have reached advanced stages in the Middle East and in other countries, while officials also said threats to American officials, including ambassadors, had been assessed in recent weeks.

The report says some intelligence indicates Iranian operatives are already active inside the United States, although one official cited in the reporting said Iran lacks the capacity to carry out all of its ambitions. US agencies are also said to believe the threat to US citizens in the Middle East is at its highest level since the US-Israel war on Iran began in February. That assessment has been linked to recent moves to withdraw staff posted in the region.

The warning matters because it raises the risk of a wider security crisis involving US personnel, diplomatic facilities and regional partners. It also comes as the United States and Israel signal they may be preparing for a new military campaign against Iran, while Tehran has reportedly threatened retaliation. The report says one possible Iranian response could include targeting communications cables in the Gulf, which would carry broader implications for regional infrastructure and security.

The latest alert fits into a longer pattern of confrontation between Washington and Tehran, with US officials already on guard over escalating attacks by Iran-backed Houthis. The report also says US agencies have identified potential targets in Europe, suggesting the concern is not limited to the Middle East. That widens the scope of the warning and underscores why diplomatic and security officials are treating the threat as urgent.

What remains unclear is how far advanced the alleged plots are, where any operation might be attempted, and whether the intelligence will lead to further withdrawals or protective measures. Washington has not publicly commented on the memo, and the reporting says officials differ on Iran's ability to carry out attacks inside the United States and elsewhere. The next developments to watch are any formal US response, changes to embassy staffing, and whether allied governments issue similar alerts.
