RIYADH, Oct. 30 (Xinhua) -- The Saudi Arabian state security agency announced on Wednesday that the Terrorist Financing Targeting Center (TFTC) blacklisted 25 Iran-linked organizations, banks and individuals, the Saudi Press Agency reported.

They have been targeted by the United States and the six Gulf countries for supporting Iran's Islamic Revolution Guards Corps' and Lebanon's Hezbollah's "terrorist" activities, Presidency of State Security said.

According to the Law of Combating the Crimes of Terrorism and its Financing, the assets of the 25 entities and individuals are frozen and any transactions with them are prohibited.

The Saudi-based TFTC is a multilateral effort among the United States, Saudi Arabia and some other Gulf Cooperation Council countries.
