Reacting to the conviction, Netanyahu called for the 20-year-old French-Israeli sargeant to be pardoned.

“This has been a hard and painful day for us all - first and foremost for Elor and his family,” Netanyahu wrote on Facebook. “I support giving a pardon to Elor Azaria.”

Netanyahu made waves before the trial even began by calling Azaria’s father to express his sympathy.

President Reuven Rivlin’s office had earlier said any talk of a pardon was premature and that an application could only be made after the judicial process had run its course.

No date has yet been announced for sentencing, and Azaria could then appeal.

Judge Colonel Maya Heller spent more than two-and-a-half hours reading out the court decision, criticising the arguments of Azaria’s lawyers.

On behalf of the three-judge panel, Heller said there was no reason for Azaria to open fire since the Palestinian was posing no threat. She called his testimony “evolving and evasive”.

“His motive for shooting was that he felt the terrorist deserved to die,” she said.

Azaria had entered the courtroom smiling, applauded by family and supporters.

But he looked shaken as the judge spoke, and after the verdict his mother yelled: “You should be ashamed of yourselves.”

Outside Israel’s military headquarters in Tel Aviv, where the court announced the verdict, dozens of Azaria supporters scuffled with police.

Shabtay Oz, a retired policeman carrying a large Israeli flag, said he never imagined himself joining a demonstration.

“But when I saw a soldier in cuffs after he shot a terrorist ... that was the point of no return.”

Right-wing leaders have called for him to be pardoned in an extraordinary public rift between politicians and the military.

Before he became defence minister in May, Avigdor Lieberman was among Azaria’s supporters. He has since backed away from his earlier stance, saying after the verdict that while he disagreed with the decision, it must be respected.

The March 24 shooting in the occupied West Bank city of Hebron was caught on video and spread widely online.

It showed Abdul Fatah al-Sharif, 21, lying on the ground, shot along with another Palestinian after stabbing and wounding a soldier, according to the army.

Azaria then shoots him again in the head without any apparent provocation.

His lawyers argued the soldier may have thought the Palestinian was wearing explosives, but others said he had already been checked for a suicide belt and no one in the video appears to be acting cautiously.

The Palestinian’s father told reporters in Hebron after the verdict that Azaria should be sentenced to life.

“For me, a just verdict will be one that is similar to the verdicts our sons (in Israeli prisons) get,” Yusri al-Sharif said.

The video was filmed by a Palestinian volunteer for Israeli rights group B’Tselem.

“The fact that one soldier was convicted today does not exonerate the Israeli military law enforcement system from its routine whitewashing of cases in which security forces kill or injure Palestinians with no accountability,” B’Tselem said after the verdict.

The case had been portrayed by some as a test of whether Israel’s military could prosecute one of its own, though many Palestinians argued Azaria was only put on trial because of the video.
