The army said the assailants fired at the soldier from a vehicle and sped away after the shooting. The attack occurred at the entrance to Ariel, a large West Bank settlement near the Palestinian city of Nablus.
The army said it found a burned car near Nablus that is connected to the shooting, but declined to provide further details.
Police spokesman Micky Rosenfeld said authorities were investigating the incident.
A previously unknown offshoot of Fatah, the movement headed by moderate Palestinian President Mahmoud Abbas, took responsibility for the shooting in a phone call to The Associated Press.
The United States' Head of Diplomacy, or Secretary of State, is an anachronistic, incompetent, meddling, intrusive, insolent and arrogant, rude individual, a brash, foul-mouthed upstart, a conceited, self-important guttersnipe and an insult to the international community, as fit for the job as a pedophile janitor in a grade school.
