Mousa Mohammed Abu Marzook (; born 9 January 1951) is a prominent Palestinian political figure and a senior member of Hamas. He was the inaugural chairman of the Hamas Political Bureau from 1992 until 1996 and subsequently served as its deputy chairman from January 1997 to April 2013, when Ismail Haniyeh succeeded him.

Early life and education

Born on 9 January 1951 in Rafah Camp, located in the Gaza Strip, Marzook's family originally hailed from Yibna (modern-day Yavne, Israel). He was the second child among nine siblings. During the Six Day War, his brother enlisted in a Palestine Liberation Organization military faction. As a youth, Marzook established connections with Sheikh Ahmed Yassin, a leader associated with the Egyptian Muslim Brotherhood.

After completing secondary education in Gaza, Marzook pursued engineering studies in Cairo between 1970 and 1976. During this period, he was actively involved with the Muslim Brotherhood. He later worked as an engineer in Abu Dhabi while continuing his engagement with Islamist circles. Notably, he was among the founding board members of the Islamic University of Gaza, founded by Islamist groups in 1978. His tenure in Abu Dhabi involved extensive travel across the Middle East to cultivate political and financial support for an Islamist Palestinian state.

In 1982, Marzook entered the United States on a student visa, where he obtained a master's degree in construction management from Colorado State University and earned a doctorate in Industrial Engineering from Louisiana Tech University. By 1991, he had relocated to Springfield, Virginia, having held a U.S. Green Card since 1990. Marzook is married and has six children.

Hamas involvement

From Hamas’s establishment in 1987, Marzook emerged as one of its principal political leaders. In 1992, he was chosen as the first head of the Hamas Political Bureau, directing its activities from Northern Virginia under the auspices of the United Association for Studies and Research. According to U.S. officials, approximately fifteen percent of Hamas's estimated $70 million yearly budget was sourced from within the United States. Journalist Shlomi Eldar attributes Hamas’s continued viability and its development of Gaza's social infrastructure largely to Marzook’s fundraising expertise and his network of donors across Europe and America. While Israel claims that portions of these funds financed attacks against it—a charge Marzook denies—he has maintained a significant leadership role as deputy chairman of the Political Bureau since 1997. Between 1998 and 2001, he resided in Jordan before moving to Damascus, Syria.

During the early 1990s, specifically between 1991 and 1995, Marzook engaged in covert negotiations with U.S. officials acting as Hamas’s representative in America. These discussions included presenting conditions for dialogue with Israel and assurances that Hamas would refrain from targeting U.S. interests. In 1992, he is reported to have traveled to Tehran functioning as Hamas’s unofficial foreign minister. On August 1, 1993, Marzook reestablished the Hamas Political Bureau in Amman, but was expelled from Jordan on July 1, 1995, following pressure exerted by Israel. Israeli authorities held him accountable for supervising factions within Hamas connected to attacks that resulted in the deaths of 47 Israelis between 1990 and 1994.

Marzook also played a foundational role in establishing the Islamic Association of Palestine.

Detention in the United States

On July 27, 1995, Marzook was taken into custody by the Immigration and Naturalization Service at John F. Kennedy Airport due to his presence on a terrorist watchlist. Both U.S. and Israeli officials identified him as the head of Hamas's political bureau, responsible for shaping the organization’s political strategies and authorizing attacks. He was also regarded as Hamas’s informal foreign minister and a central figure in fundraising efforts. Marzook was held at the Manhattan Correctional Center. His lawyer, Stanley L. Cohen, conceded that Marzook supported Hamas but refuted claims of his leadership status. Nevertheless, Imad Falouji, a Hamas official in Gaza appointed by Marzook, effectively confirmed his leadership position.

A U.S. judge determined there was "probable cause" connecting Marzook to bombings in Israel. Two months following his arrest, Israel formally requested his extradition. Cohen continued to serve as Marzook’s legal counsel throughout this period.

Hamas Leadership Following Detention

After spending 22 months in U.S. custody, Marzook was deported to Jordan in May 1997 once Israel withdrew its extradition appeal. As part of the arrangement, he gave up his U.S. residency status. During a press briefing, Marzook acknowledged his role leading Hamas’s political faction and declared that the organization would cease targeting Israeli civilians, although he stopped short of condemning attacks against Israelis.

In 2003, the Central Bank of Jordan froze assets belonging to several Hamas leaders, including Marzook, politburo chief Khaled Mashal, founder Ahmed Yassine, and senior figures Osama Hamdan and Imad al-Alami.

Following the election of Ismail Haniyeh as deputy leader of Hamas by the Hamas Shura Council in April 2013, Marzook was named one of two deputies charged with overseeing external affairs. Meanwhile, Khaled Mishaal focused on internal matters within the Palestinian Territories.

Exile Residency

By 2012, Marzook was residing in New Cairo, Egypt. At the onset of the Gaza war in 2023, he was living in Doha, Qatar.

U.S. Legal Proceedings

In 1995, the U.S. Treasury Department designated Marzook as a Specially Designated Terrorist, and he remains listed on the Specially Designated Nationals list under multiple name variants and the alias "Abu-'Umar."

In 2002, a federal grand jury in Dallas charged Marzook with conspiracy to violate U.S. laws prohibiting terrorist financing. The indictment alleged collaboration with Richardson, Texas-based InfoCom Corporation and its staff to disguise financial transactions, including a $250,000 investment structured with profit-sharing arrangements.

In 2004, Ismail Elbarasse—an aide to Marzook—was arrested after authorities discovered bank documents linked to Marzook during a search. Elbarasse was identified as an unindicted co-conspirator in a federal indictment accusing Marzook of raising millions for Hamas.

That same year, a U.S. court indicted Marzook in absentia for orchestrating and funding Hamas operations.

Conversation with The Forward

In April 2012, Marzook granted his inaugural interview to a Jewish media outlet, The Forward. He emphasized that any pact between Israel and the Palestinian Authority would necessitate a referendum encompassing all Palestinians, including those in Gaza. Marzook characterized such an arrangement as a hudna (a temporary cease-fire) rather than a formal peace treaty and suggested that Hamas might revise its conditions if it assumed power. He clearly stated, "We will not recognize Israel as a state," likening the future relationship to that of Lebanon or Syria with Israel—essentially an armistice.

The interview with The Forward took place over two days at Marzook's residence in New Cairo. The publication also included insights from eight distinguished observers of the Middle East peace process, featuring analysts and activists from various perspectives.

Operation Pillar of Defense

In the aftermath of the eight-day confrontation between Israel and Hamas in November 2012, Moussa Abu Marzouk, the second-in-command of Hamas, asserted that the organization would persist in producing and smuggling arms into Gaza.

Gaza war

Following the October 7 attacks, Marzook gave interviews to both the BBC and the Economist, denying that Hamas deliberately targeted civilians. Concerning the Re'im music festival massacre, he described it as a "coincidence," implying that the attackers may have confused civilians with soldiers who were resting.

When asked about Hamas's extensive construction of 500 km of tunnels contrasted with the absence of civilian shelters in Gaza, Abu Marzouk responded that these tunnels serve to protect Hamas militants, while asserting that safeguarding civilians is the responsibility of both the UN and Israel.
