Federal agents in Los Angeles have arrested 7 Iranians. American officials have charged the Iranians with using false information to gain money for terrorist organizations. The officials said the Iranians told people they were collecting the money for humanitarian aid. Instead, the officials said, the group gathered the money to buy weapons for a terrorist group called the People's Mojahedin. The group is suspected of trying to overthrow the Government of Iran. The arrests were made after a 3-year investigation.
