FBI spokeswoman Laura Eimiller says the defendants are under arrest for plotting to bomb government facilities and public places.
According to the federal complaint unsealed Monday during initial appearances, 34-year-old Sohiel Omar Kabir introduced two other California men to the radical Islamist doctrine of Anwar al-Awlaki, a deceased al-Qaida leader.
Authorities allege Kabir traveled to Afghanistan and communicated with the two - 23-year-old Ralph Deleon and 21-year-old Miguel Alejandro Santana Vidriales - so he could arrange for their travel to join him and meet with his contacts for terror organizations. They later recruited 21-year-old Arifeen David Gojali.
The complaint says Deleon and Santana told an FBI source of their plans to engage in "violent jihad."
