A chilling order echoed from the highest levels of power in Iran. Ayatollah Khamenei, the Supreme Leader, unleashed a brutal crackdown on burgeoning protests, a wave of repression carried out not solely by Iranian forces, but by a network of foreign fighters brought into the country.
For years, Iran has cultivated relationships with Islamist militant organizations throughout the Middle East, establishing itself as a destabilizing force in the region. This wasn’t simply about funding or training; it was about building a shadow army, a force capable of acting with deniability and ruthlessness, and now, that army was turning inward.
The regime’s strategic thinking is rooted in its unique position. Predominantly Shia in a largely Sunni Arab world, Iran has long felt isolated. This has fueled a strategy of creating proxy networks – groups that extend influence and provide a shield for internal repression.
The first wave arrived in early January 2026: nearly 5,000 Iraqi Shia militia fighters crossing the border. What began as a trickle of several hundred quickly swelled as the crackdown intensified, a clear signal of the regime’s desperation and willingness to employ any means necessary.
Among the most prominent was Kataib Hezbollah, a U.S.-designated Foreign Terrorist Organization deeply embedded within Iran’s sphere of influence. Its commander issued a stark warning – any attack on Iran would be met with retaliatory strikes against American bases across the Middle East, framing the defense of the Islamic Republic as a sacred duty.
Harakat al-Nujaba, another U.S.-designated group, also deployed fighters, cleverly disguised as religious pilgrims traveling to holy sites. European military sources confirmed their presence in Iranian cities, noting their chillingly efficient application of combat experience honed in the brutal conflict in Syria – now turned against their own people.
The flow continued, masked by religious journeys. Fighters from Kataib Sayyid al-Shuhada arrived through multiple border crossings, gathering in Ahvaz before being dispersed to protest hotspots. Even the Badr Organization, though not formally designated a terrorist group by the U.S., openly declared its support for suppressing the unrest.
The logistics were stark. Buses, packed with roughly 50 fighters each, streamed across the border. Flights from Najaf to Tehran and Mashhad doubled in frequency. The regime reportedly paid these foreign fighters around $600 a month, a grim incentive to quell dissent with force. The deployment aimed to prevent any sympathy or hesitation from Iranian security forces – to create a barrier between those enforcing the crackdown and the people they were suppressing.
The ranks swelled further with the Fatemiyoun Brigade, Afghan Shiite fighters originally recruited by Iran’s IRGC to fight in Syria. Stranded after the shifting tides of that conflict, they were redirected to a new, horrifying purpose: silencing Iranian voices. Reports emerged of their direct involvement in killings during the January crackdown, operating openly in civilian neighborhoods under the cover of darkness.
Alongside them fought the Liwa Zainabiyoun, Pakistani Shiite fighters also recruited for the Syrian war. Like the Fatemiyoun, they were implicated in the killings, working in tandem with Iranian security forces on the streets and within residential areas.
Even Hezbollah’s involvement, though more limited, was significant. While constrained by its own internal struggles, the group condemned the protests as a foreign conspiracy, a thinly veiled attempt to distance itself while still signaling support for the regime.
Overseeing this complex and brutal operation was Ali Larijani, secretary of the Supreme National Security Council, the key architect of the crackdown. The regime’s reliance on foreign militias, sources revealed, stemmed from a deep-seated fear – a fear that Iranian police might refuse to fire on unarmed civilians, or simply lack the capacity to control the widespread unrest erupting in over 100 cities.
This wasn’t merely about suppressing protests; it was about creating a failsafe against any future challenge to the regime’s authority. By deploying foreign proxies, Iran had built a force willing to do what its own security forces might hesitate to do – fire on its own people.
