(CNN) Two Georgia teenagers appeared in court Thursday on charges that they planned to attack their high school.

Alfred Dupree and Victoria McCurley, who were arrested Wednesday, face several charges including attempted murder and making terroristic threats, according to a statement from the Cherokee County Sheriff's Office. Both are 17 but are being charged as adults.
