An Israeli Defence Force soldier appeared in a military court on Tuesday after he was caught on video shooting a Palestinian in the head while he laid on the ground.
Prosecutors requested to extend the remand of the soldier for another nine days until April 7.
"The suspicion emanating from the investigation is that the shooting was carried out intentionally and without need," prosecutor Lieutenant Colonel Adoram Rigler told the court.
The court decision is expected to be announced later in the day.
During the trial, many of his supporters protested in the court.
The protesters wanted authorities to release the soldier despite the video clearly showing the Israeli soldier shooting the teenager in the head, spilling his blood all over the pavement without any apparent provocation.

Military top brass have condemned the incident and Israel Defence Minister Moshe Yaalon has vowed that the incident will be treated with the "utmost severity".
The incident has increased political tension in the country.
Israeli rights group B'Tselem immediately condemned the incident while Palestinians also denounced the war crime.
The United Nations also condemns the Israeli soldier's 'gruesome' killing of the wounded Palestinian teen in the West Bank.
“I strongly condemn yesterday's apparent extrajudicial execution of a Palestinian assailant in Hebron in the occupied West Bank," UN Special Coordinator for the Middle East peace process Nickolay Mladenov said in a statement.
"This was a gruesome, immoral and unjust act.”
He called on Israeli authorities to “bring to justice” the perpetrator of the incident.
Israeli Prime Minister said the soldier’s behaviour was not in accordance with the army’s values but Palestinian critics suggested otherwise.
However, far-right politicians have advocated the soldier, and members of his family publicly claimed that he was being subjected to public 'lynching' and would not face a fair trial.
Israeli politicians were also heated up over the debate of Israel’s response to the current wave of violence. Israelis have been accused of using excessive force in many other cases, all of which they have generally denied.
