Cantor Fitzgerald, the bond trading firm that lost two thirds of their employees on September 11, is suing the Saudi entity for $7 billion in losses: Cantor Fitzgerald Sues Saudis for Losses. (Hat tip: zulubaby.)

The company, in a $7 billion lawsuit filed Thursday in U.S. District Court in Manhattan and made public Friday, also named dozens of other defendants, including numerous banks and Islamic charities, in a bid to hold them accountable for its losses in the terrorism attack.

A message for comment left with the Saudi Arabia embassy in Washington was not immediately returned.

The lawsuit noted that it carried many of the same defendants, transactions, events and questions of law as an earlier $300 billion lawsuit brought by insurance companies against terrorist groups, companies and countries supporting terrorism. That lawsuit, which also names Saudi Arabia, is still pending.

The Cantor Fitzgerald lawsuit took particular aim at Saudi Arabia, saying the kingdom “knew and intended that these Saudi-based charity and relief organization defendants would provide financial and material support and substantial assistance to al-Qaida.”

According to the lawsuit, Saudi Arabia engaged in a pattern of racketeering as it participated directly or indirectly in al-Qaida’s work through its “alter-ego” charities and relief organizations, which it funded and controlled.

The lawsuit alleged that Saudi Arabia materially supported al-Qaida by helping to raise money for it, by knowingly and intentionally employing al-Qaida operatives, by laundering its money and by providing al-Qaida with safe houses, false documents and ways to obtain weapons and military equipment.

“This uninterrupted financial and material support and substantial assistance enabled the al-Qaida defendants to plan, orchestrate and carry out the Sept. 11 attacks,” the lawsuit said.
