TEL AVIV, Israel (AP) — An Israeli soldier was convicted of manslaughter on Wednesday in the deadly shooting of a badly wounded Palestinian attacker, capping a nine-month saga that has deeply divided the country.

The verdict, which marks an extremely rare case of an Israeli military court convicting a soldier for lethal action taken in the field, threatened to deepen the rift. Military commanders have condemned the soldier’s conduct while much of the public, along with leading members of the nationalist ruling coalition, have rallied behind him.

With Sgt. Elor Azaria’s sentencing believed to be weeks away, the country now faces a heated debate over whether he deserves clemency. Within minutes of the verdict, leading politicians were already calling for him to be pardoned. Under Israeli law, the country’s largely ceremonial president has the authority to issue a pardon.

Hours after the verdict, Prime Minister Benjamin Netanyahu called for Azaria to be pardoned, plunging into the raging political debate that has divided the country and putting himself at odds with the military. On his Facebook page, Netanyahu wrote: “I support granting Elor Azaria a pardon.” He also urged the public to support the army and its commanders.

Azaria, an army medic, was caught on video in March fatally shooting the wounded Palestinian who had stabbed a soldier in the West Bank city of Hebron. The Palestinian, Abdel Fattah al-Sharif, was lying on the ground and already unarmed when Azaria shot him in the head.

In delivering the verdict, which lasted nearly three hours, Col. Maya Heller, head of a three-judge panel, rejected Azaria’s defense in painstaking detail.

She said there was no evidence to support his contradictory claims that the attacker was already dead or that he posed any threat at the time, telling him he “couldn’t have both sides of the stick.” She called his testimony “unreliable” and said he “needlessly” shot the assailant.

“We found there was no room to accept his arguments,” she said. “His motive for shooting was that he felt the terrorist deserved to die.”

Azaria faces a maximum penalty of 20 years behind bars, though he is not expected to receive that much time. The military said he would be sentenced on Jan. 15. The defense team said it would appeal.

The 20-year-old Azaria entered the court smiling and appearing confident, and he was embraced by a few dozen relatives and friends. But as the verdict was delivered, he stared gloomily ahead, and tensions quickly boiled over in the cramped, crowded courtroom.

Members of Azaria’s family clapped sarcastically as the decision was delivered, some screaming “Our hero!” A female relative was kicked out of the courtroom for screaming at the judges, and a second woman stormed out, shouting, “Disgusting leftists.”

After the judges walked out, Azaria’s mother, Oshra, screamed, “You should be ashamed of yourselves.” Azaria tried to comfort her and calm her as she wailed. Another family member whipped his jacket at a female reporter, missing his target and instead hitting another relative.

Hundreds of the soldier’s supporters, many of them young religious men wearing skullcaps, gathered outside the military court in Tel Aviv ahead of the verdict. The crowd, holding large Israeli flags and banners, periodically scuffled with police.

Some demonstrators chanted veiled death threats against the Israeli army’s chief, Lt. Gen. Gadi Eizenkot, insinuating he would face the same fate of slain Israeli Prime Minister Yitzhak Rabin, assassinated 20 years ago by an ultranationalist Israeli.
