Nearly 200 family members of Americans slain in the October 7 Hamas massacre have filed a bombshell federal lawsuit against Bashar Masri — a celebrated Palestinian-American developer — accusing him of knowingly aiding and abetting the terrorist group behind the deadliest attack on Jews since the Holocaust.

Masri, long hailed in elite diplomatic circles as a “moderate” visionary and touted by 60 Minutes as a beacon of hope in the West Bank, is now facing explosive allegations that he helped build the very infrastructure Hamas used to wage war — including tunnels, rocket launch sites, and command centers hidden beneath his luxury hotels and industrial parks in Gaza.

Filed in D.C. federal court, the suit claims Masri’s companies provided Hamas with utilities, facilities, and logistical cover — all while raking in millions from international aid agencies and green energy initiatives. One alleged hotel, the Blue Beach, became a literal gateway to terror, with tunnel shafts descending from guest rooms into Hamas’ underground network. Another, the Al Mashtal Hotel — where world leaders once gathered — allegedly doubled as a command center for Yahya Sinwar, the mastermind of the Oct. 7 atrocities.

“Defendants provided services that legitimized Hamas and protected its operations from Israeli and U.S. action,” wrote lead attorney Lee Wolosky, a former national security official under four U.S. presidents.

Masri, a naturalized U.S. citizen with deep ties to Washington and Harvard’s Kennedy School, was still advising President Trump’s hostage envoy as recently as last month. Now, families of Americans murdered in the Oct. 7 attack — including those of Hersh Goldberg-Polin, Itay Chen, and victims from the Nova music festival — are demanding justice under the Anti-Terrorism Act.

The complaint doesn’t just allege moral complicity — it outlines a complex network of financial, logistical, and political support that allegedly enabled Hamas to turn real estate into weaponry. Masri’s $350 million “futuristic city” of Rawabi was bankrolled largely by Qatar — a country that also funds Hamas. His Gaza properties, the lawsuit claims, received U.N., EU, and World Bank dollars — and then funneled electricity into Hamas’ tunnel system via solar panels on his hotels and factories.

Above ground, the Gaza Industrial Estate looked like a hub of economic progress, producing everything from pharmaceuticals to soft drinks. Below ground, it was allegedly a launchpad for bloodshed — complete with rocket infrastructure, anti-tank emplacements, and escape tunnels stretching toward Israel.

The lawsuit also names Masri’s companies, including PADICO and Massar International, as co-defendants. Notably, the filing includes photos of Masri with Hamas officials and claims of joint business ventures with figures like Hamas Deputy Minister of Economy Abdel Fattah Zrai — killed by the IDF last year.

The lawsuit accuses Masri of three violations under the Anti-Terrorism Act: aiding and abetting Hamas, conspiring with the group, and providing material support to a U.S.-designated foreign terrorist organization.

Masri’s office denied the allegations in a statement, calling them “baseless,” and insisted he “unequivocally opposes violence of any kind.”
