Washington: The United States froze the assets of three Gulf-based militants on Thursday, saying they provided financial and material support to Al Qaida.

"These three dangerous individuals must be stopped from further facilitating terrorism," said Stuart Levey, Treasury's undersecretary for terrorism and financial intelligence.

"The global community should act swiftly to prohibit them from using the financial system and from travelling internationally," Levey said.

Any assets these men have under US jurisdiction will be frozen, and Americans will be prohibited from doing business with them, the Treasury Department said.

Al Qaida connection

The three include Khalifa Mohammad Turki Al Subaiy, described by Treasury as a financier and facilitator who has provided financial support to, and acted on behalf of, Al Qaida senior leadership.

Treasury named the others as Adil Mohammad Mahmoud Abd Al Khaliq, who it says has provided financial, material, and logistical support to Al Qaida and the Libyan Islamic Fighting Group; and Abd Al Rahman Mohammad Jaffar Ali, a financier who it says facilitated the movement of money to a senior Al Qaida individual in Iran and also provided his personal funds for use by an Al Qaida recruit.
