Both the Zainabiyoun and Fatmiyoun Brigades are supported by Iran's
Islamic Revolutionary Guard Corps (IRGC) and are important parts of the Iranian government's construct which uses such proxy groups as a core strategy for deterrence across the region, which includes its main proxy
Hezbollah and its allies:
Kata'ib Hezbollah,
Kata'ib Sayyid al-Shuhada,
Hezbollah Al-Nujaba,
Ansar Allah (popularly known as the Houthis) and
Hamas have been a part of Iran's strategy of deterrence from engaging in a conventional full-scale conflict with
Israel and its
Arab allies despite the limited employment of both the Zainabiyoun and Fatmiyoun brigades composed of Pakistani and Afghan nationals have successfully demonstrated Iran's capability to mobilize Shia ecosystems not only in the
Middle East but on its own borders and further afield during the
IsraelHezbollah war and
Gaza war. These resistance forces of Pakistanis and Afghans, formerly based in Syria, are expected to carry out direct attacks on
Israel while operating as a part of
Hezbollah, the
Islamic Resistance in Iraq or the
Houthis. Iran's military strategy in
Lebanon and
Iraq is based on the concept of liberation of
State of Palestine and elimination of
Zionist,
State of Israel including forward defense. It entails engaging adversaries beyond its own territory to prevent threats from reaching its border. A key pillar of this strategy is a network of Iran's
IRGC-linked armed groups across the region known as the
Axis of Resistance. This includes
Hezbollah in Lebanon various Shitte Militias in Iraq, Yemen and Iran sponsored militias in Syria as well as the
Palestinian resistance forces specifically
Hamas,
Palestinian Islamic Jihad and their subgroups in the
Palestinian territories. Reportedly, Iran supports 20 or more groups/organizations directly or indirectly all over world, strategically planned and revived by the former
IRGC officer
Qasem Solemani, described as a "genius of
asymmetric warfare", in order to counter the
imperialist influence and interests of the
United States,
Israel and their allies. Former
Mossad director
Yossi Cohen said Soleimani's strategies had "personally tightened a noose around Israel's neck". After the United States and Israel
attacked Iran in January 2026, the group pledged its support for Iran and its willingness to fight against Israeli and American interests in the Middle East. The group said in a statement, "Your blood is our blood. Our hearts, souls, and minds stand with you," and also that "the people of Pakistan stand shoulder to shoulder with you." The group issued a warning, similar other groups in the Axis of Resistance. It said that any direct involvement by the United States in a war or conflict with Iran, or that if any harm reaches, or is done to the Iranian Supreme Leader, Syed Ali Khamenei, it would provoke a response worldwide that will targeting American assets, especially in West Asia and Pakistan. The statement concluded with "Signed in our blood, the soldiers of Hajj Qassem Soleimani." ==Designation as a terrorist organization and ban==
