Amateur video appearing to show an Israeli soldier killing an already wounded Palestinian attacker has sparked uproar in Israel.
As the Israeli military pressed on with an investigation, nationalistic politicians accused the army of abandoning the soldier, while political doves bemoaned the erosion of the nation's morals.
Palestinians, meanwhile, said the shooting proved their claims that Israel is guilty of using excessive force and carrying out extrajudicial killings.
The shooting took place last Thursday in Hebron, the volatile West Bank city that has been a focal point of the latest wave of Israeli-Palestinian violence.
The military said two Palestinians stabbed and wounded an Israeli soldier before troops shot and killed the pair.
In a video released by the Israeli human rights group B'Tselem, one of the attackers appears to still be alive after the initial shooting.
The video, taken by a Palestinian volunteer for the group, shows the wounded attacker lying on the ground, slowly moving his head. About a minute later, a soldier raises his rifle, cocks the weapon and fires. Blood is then seen streaming from the Palestinian's head.
The Israeli military quickly arrested the soldier and opened an investigation into what it said appeared to be a "grave breach" of its values. A military court has ordered the soldier to remain held until Tuesday while the investigation continues.
Lt Col Peter Lerner, a military spokesman, said that commanders had already reported the shooting to their superiors before the video emerged.
The sister of the soldier, who was not identified, accused the military of publicly convicting her brother, and several nationalistic lawmakers came to his defence, accusing detractors of abandoning him before he was given a fair hearing.
Naftali Bennett, leader of the hardline Jewish Home party, said the shooting should be investigated, but criticised politicians and the media for rushing to condemn the soldier.
Over the weekend, hundreds of people protested in support of the soldier outside the prison.
But Sima Kadmon, a commentator for the Yediot Ahronot daily, criticised social media posts defending the soldier, and also lashed out at the apparent apathy shown by soldiers in the video after the Palestinian was shot.
The shooting came amid a six-month wave of Palestinian stabbings, shootings and car-ramming attacks that has killed 28 Israelis and two Americans. Over the same time, at least 188 Palestinians have died by Israeli fire. Israel says most were attackers, and the rest died in clashes with Israeli security forces.
