Concerns are mounting regarding potential retaliatory attacks across Europe, as Iran reacts with heightened aggression following the recent death of the Ayatollah. German intelligence official Marc Henrichmann, a member of the Parliamentary Control Committee, expressed strong warnings in an interview with Süddeutsche Zeitung, highlighting that the violent incidents in the Middle East could extend their reach beyond regional borders.
Henrichmann remarked, “The escalation in the Middle East doesn’t just affect the region itself,” pointing out Iran’s historical propensity to conduct operations internationally. He emphasized that the threat from “Iranian sleeper cells in Europe cannot be ruled out,” underlining the necessity for heightened vigilance in the face of these developments.
This concern is echoed by other Western leaders. Reports from the New York Times have indicated that US officials, speaking anonymously, have observed a surge in “chatter,” or electronic communications among terrorist groups that signals potential attack planning. There is a rising apprehension among American intelligence and counterterrorism officials regarding Tehran’s possible use of proxies such as the Houthis in Yemen, who may target Western shipping in the Red Sea.
In Europe, the alarm extends to the possibility of attacks orchestrated by Hezbollah sleeper cells, or affiliates of Al Qaeda, aimed at American installations and embassies. Although one senior US official noted increased activity among terrorist cells, the likelihood of imminent attacks remains uncertain.
The phenomenon of sleeper cells—covert groups that lay low before executing acts of terrorism—has been particularly noted in recent Iranian operations. A significant incident in May of last year underscored these threats, as UK authorities prevented a substantial terror attack merely hours from execution, with Iranian nationals among those arrested.
Reports of Iranian nationals being recruited for such sleeper cells have further intensified concerns, with testimonies indicating coercive recruitment tactics and deceptive initial engagements. An Iranian in London recounted experiences of being approached for missions tied to Tehran, suggesting systematic attempts to integrate operatives within Western societies.
As Iran enters a period of mourning for the Ayatollah, the intensity of its backlash has already manifested in violence, including a recent attack in Israel that claimed eight lives. Iranian President Masoud Pezeshkian declared in a televised address that the nation aims to leave its adversaries “hopeless,” signaling a potentially more aggressive stance from Iran’s newly established leadership.
With the situation evolving rapidly, the international community remains on alert, placing emphasis on preparedness and vigilance to mitigate the risks posed by Iranian proxies and sleeper cells in Europe and beyond.
