U.S. agencies have warned that Hizbullah has been recruited by Syria to prepare massive retaliatory attacks in any confrontation between Damascus and Washington.
U.S. officials said the CIA and State Department have warned that Iran and Syria could employ Hizbullah to launch attacks against U.S. interests in the Europe, the Middle East and North America. They said the Shi'ite movement is seen as more entrenched in the West than Al Qaida and could have up to 12 cells in the United States alone.
