JERUSALEM — Amateur video appearing to show an Israeli soldier killing an already wounded Palestinian attacker sparked uproar in Israel on Sunday, reflecting the deep divisions in the country following six months of violence.

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.

Military officials also have cast doubt on the soldier’s claim that he believed the Palestinian was carrying explosives.

On Sunday night, B’Tselem released a second video it says shows the same soldier at the scene shaking hands with Baruch Marzel, a well-known ultranationalist, after the shooting.
