You can look to press charges against minors--they are not officially exempt from the criminal law--but it's not likely much will happen: minors are treated very leniently by the criminal justice system. My own daughter was attacked by another teenager with a shovel and suffered a serious concussion, but despite finding her attacker guilty, the court declined to punish her--no community service, no fine, no jail time, etc. So while you have the right to press charges, nothing may happen from it.If your son was injured, you could also sue the minors' parents for his injuries and any medical costs you incurred. A minor's parents or legal guardians are liable for the injuries their minors inflict.
