In Washington policy circles, Yemen’s Islah Party has cultivated an image: a broad, nationally rooted coalition, imperfect but indispensable to stability in a fractured country, and the biggest party in the internationally recognized government.
The lobbying effort behind that image is robust. As recently as December 2025, a high-level Islah delegation was working the corridors of the British Parliament, presenting the party as a moderate national force with no meaningful connection to the global Muslim Brotherhood network.
When the Trump administration began seriously debating whether to designate the Muslim Brotherhood as a Foreign Terrorist Organization, Islah’s leadership did what it always does under pressure: It issued denials. The party declared in 2013, again in 2016, again in 2018, and yet again in September 2025 that it maintains no “organizational or political ties” to the Brotherhood. Organizations that are genuinely independent do not need to deny their independence on a four-year cycle.
Islah’s origins lie in the Islamic Front, a Muslim Brotherhood-affiliated militia supported by Saudi Arabia during the Cold War.
The evidence assembled from U.S. Treasury designations, federal court records, and the party’s own public statements tells a different story—one that U.S. policymakers no longer can overlook.
Islah’s origins lie in the Islamic Front, a Muslim Brotherhood-affiliated militia supported by Saudi Arabia during the Cold War. When Yemen unified in 1990, that militia regrouped under the banner of the Islah Party. Though widely characterized as Islamist, Islah is in practice a coalition that includes the Hashid tribal confederacy, a Muslim Brotherhood political faction, prominent businessmen, and smaller groups, some with alleged ties to Al Qaeda. This architecture was deliberate: tribal and national trappings layered over a transnational ideological core to render the Brotherhood’s Yemeni branch resistant to scrutiny.
The Muslim Brotherhood’s presence in Yemen dates to the 1960s, when Abd al-Majid al-Zindani led a group of clerics in establishing a religious education network across northern Yemen. Zindani would co-found Islah in 1990 and remain both its most consequential figure and the most damning evidence against the party’s claims of independence.
In January 2004, the U.S. Treasury Department designated Zindani as a Specially Designated Global Terrorist, citing credible evidence that he had “a long history of working with [Osama] bin Laden, serving as one of his spiritual leaders,” and had “played a key role in the purchase of weapons on behalf of Al Qaeda and other terrorists.” The United Nations followed suit weeks later.
The designations did not end there. A U.S. federal lawsuit identified Zindani as a coordinator of the October 2000 suicide bombing of the USS Cole in Aden harbor, an attack that killed seventeen American sailors. He also served on the board of the Union of Good, an umbrella organization the United States designated for financing Hamas, and maintained close ties with global Brotherhood leadership, including Yusuf al-Qaradawi. Zindani died in April 2024 in Turkey, where he had spent his final years. That Turkey, the Brotherhood’s most reliable supporter, served as his final refuge was itself a statement.
The question that should occupy Washington is straightforward: How has a party whose co-founder was a U.S.-designated terrorist, a spiritual mentor to Osama bin Laden, and a financier of Hamas continue to operate as a recognized partner in Yemen’s internationally-backed government?
Islah’s denials collapse most completely when measured against the U.S. government’s own sanctions record. In December 2016, Treasury designated Al-Hasan Ali Ali Abkar, head of Islah’s al-Jawf provincial branch, for providing financial and material support to Al Qaeda in the Arabian Peninsula. The following year, Washington sanctioned Khalid Ali al-Arada, a member of Islah’s leadership council and brother of Sultan Ali al-Arada, a Presidential Leadership Council member and governor of Marib, for being an Al Qaeda in the Arabian Peninsula operative. Rather than condemn al-Arada, Islah “condemned his designation, calling the underlying intelligence ‘misleading and false.’”
Islah’s denials collapse most completely when measured against the U.S. government’s own sanctions record.
In October 2024, the Treasury went further. It designated Hamid al-Ahmar—son of Islah co-founder Sheikh Abdullah al-Ahmar, as a “prominent international supporter of Hamas,” having managed a $500 million Hamas investment portfolio that enriched both the movement and Islah’s own leadership. Hamid al-Ahmar now operates from exile in Turkey, coordinating Muslim Brotherhood parliamentarians across the globe. Turkish support goes beyond ideological sympathy and provides financial architecture—a $500 million portfolio managed by a leading Islah figure, for Hamas, from Turkey. That is not the behavior of a locally-rooted national party.
Having served as Yemen’s foreign minister, I witnessed firsthand how thoroughly Islah had penetrated every institutional lever of the internationally recognized government, not as a coalition partner exercising proportional influence, but as a controlling apparatus that shaped appointments, resource allocation, and diplomatic positioning from within. What Washington sees as a flawed but manageable partner is, in structural terms, a Brotherhood-run administration operating beneath a national flag.
If any doubt remained about where Islah’s allegiances lie, the party’s response to the Hamas massacres of October 7, 2023, settled it. On the one-year anniversary of the attack, Islah’s official website described the massacre as “a preemptive strike launched by the al-Qassam Brigades against the Israeli occupation,” celebrating Yemeni crowds who took to the streets in governorates such as Marib and Taiz. When Israeli forces killed Hamas leader Yahya Sinwar, Islah praised him for being martyred while “fighting side by side with his people, carrying his weapon.”
This is the official voice of a party that insists it has severed ties with the Brotherhood’s international network. The language is identical to communiqués issued from Istanbul and Doha. The script is the same; only the letterhead differs.
The contradictions in Islah’s conduct extend beyond rhetoric. Despite its formal role in the anti-Houthi coalition, prominent Islah figures continue to operate openly in Houthi-controlled Sanaa, a coexistence that strains any claim of enmity. More recently, following military pressure against Southern Transitional Council forces, Islah units began redeploying into southern provinces. Their advance has coincided with a conspicuous resurgence of Al Qaeda in the Arabian Peninsula in those same areas, and with Al Qaeda in the Arabian Peninsula’s opening acts, including the targeted assassination of Southern Transitional Council leaders. Whether by design or operational convenience, the pattern is consistent with a decade of overlap between Islah networks and jihadist infrastructure.
Islah does not merely tolerate extremism within its ranks; it defends it, funds it, and eulogizes its perpetrators.
U.S. diplomats long have resisted designating Islah, arguing that doing so would destabilize Yemen’s fragile internationally recognized government, of which Islah holds two seats on the Presidential Leadership Council. This reasoning inverts the logic of counterterrorism policy. The United States typically does not argue that it cannot sanction a terrorist-linked organization because the organization holds government positions, particularly when those positions were acquired through institutional capture, not democratic legitimacy.
The pattern is consistent and prosecutable: a co-founder designated for supporting Al Qaeda and bin Laden; provincial and council-level leaders sanctioned for Al Qaeda in the Arabian Peninsula ties; a senior figure managing a half-billion-dollar Hamas portfolio; official party statements celebrating mass murder; and a ground presence in the south that moves in lockstep with Al Qaeda in the Arabian Peninsula’s re-emergence. Islah does not merely tolerate extremism within its ranks; it defends it, funds it, and eulogizes its perpetrators.
Designating Islah is not a step that would unravel Yemen’s peace process. It is a prerequisite for any peace process worth the name. A political settlement that grants institutional legitimacy to a Brotherhood front with documented ties to Al Qaeda, Hamas, and the global Islamist network does not produce stability; it licenses it. Washington already holds the evidence. What it lacks is the resolve to act on it.
