John T Booker Jr was making final preparations to carry out the suicide attack on behalf of the Islamic State (IS), the FBI said.Mr Booker previously had tried to join the Army, but was denied entry because of internet posts about "jihad".Authorities say that US personnel were never in danger.He is the latest American to be arrested for attempted support of IS. Two Chicago men were arrested in late March for attempting to provide material support to the organization. In earlier this month two women in New York City were arrested on suspicion of planning to use a weapon of mass destruction.Booker, also known as Mohammed Abdullah Hassan, enlisted in the military "with the intent to commit an insider attack against American soldiers," according to the FBI complaint.He had "formulated several plans for committing jihad once enlisted", including shooting soldiers on the firing range and kidnapping a high-ranking officer.
