WASHINGTON, Aug 15: More than 500 people who lost loved ones in the September 11 attacks are to file a civil suit on Thursday against Sudan, Muslim-run charities, members of the Saudi royal family and several other groups they accuse of helping to finance the Al Qaeda, sources close to the families said.

The suit by an organization called “9/11 families united to bankrupt terrorism” is also aimed at Osama bin Laden and the Taliban.

In addition, it targets seven international banks, eight Muslim-run charities, several financiers and three Saudi princes — Mohammed al-Faisal al-Saud, Turki al-Faisal al-Saud and Sultan bin Abdul Aziz al-Saud.

Seeking 1,000 trillion dollars in damages from the groups and one trillion dollars from the individuals, the plaintiffs endeavor to “force the sponsors of terror into the light and subject them to the rule of law”, according to the suit that was filed in a federal court here on Thursday.

The banks named in the suit are: Al Baraka Investment and Development Corporation, National Commercial Bank, Faisal Islamic Bank, Al Rajhi Banking and Investment, Al Barakaat Exchange LLC, Dar Al Maal Al Islami and Al Shamal Islamic Bank.

The Islamic groups it singles out are: International Islamic Relief Organization, Sanabel Al Kheer, Muslim World League, Saar Foundation, Rabita Trust, Al-Haramain Islamic Foundation Inc, Benevolence International Foundation and the World Assembly of Muslim Youth.—AFP
