But in an apparent reference to Hamas, she also said "the use of civilian presence for the objective of shielding military activities" could also be a war crime. In 2017, the PA imposed a 30 percent pay cut on employees in Gaza, causing civil servants to take to the streets in protest, and forcing 6,000 into early retirement.
The killing of Palestinian journalist Yaser Murtaja by an Israeli sniper, with what the head of Reporters Without Borders called "an intentional shot", understandably got worldwide headlines.
He said the journalist had been paid by Hamas since 2011 and had used a drone to collect information on Israeli forces along the border.
The video, which emerges after 31 Palestinians have been killed in Gaza by sniper bullets shot from within Israel, have gained worldwide condemnation.
Israel claims it has only opened fire when necessary to stop damage to the border fence, infiltration and attempted attacks.
Jamal Zahalka of the Joint List, a political alliance of four Arab-dominated parties in Israel, said the video "indicates to the rule".
Israeli fighter jets struck a Hamas target in the Gaza Strip on Monday in response to two explosive devices found near Israel's border with the territory, the military said, amid a flare-up in deadly Israeli-Palestinian violence.
Israel has faced mounting questions over its use of live fire after 10 days of protests and clashes along the Gaza Strip border.
In a statement by the Palestine Liberation Organisation (PLO), chief negotiator Dr Saeb Erekat called the video "a reflection of the cruel mentality of Israel's military occupation and the drive of its systematic shoot-to-kill policy against the Palestinian civilians".
Media sources in Qalqilia, in northern West Bank, said several army jeeps invaded Azzoun town, east of the city, searched homes and abducted a teenage boy, identified as Yassin Rajeh Shbeita, 16, in addition to Bassam Nabil Hussein.
The army claimed the video seemed to show an incident that happened "a number of months ago" and said that it "will be thoroughly investigated". Other soldiers are heard cursing the man and then cheering when he falls.
Health officials in Gaza said they had no information about the man shot in the video and that his identity was unknown to them.
For Israelis and Palestinians, the video was a reminder of another case from March 2016 that showed an Israeli soldier shooting dead a prone Palestinian assailant.
After a one-day investigation of the incident, the military said in a statement released on Tuesday that "it should be noted that these do not suit the degree of restraint expected of Israel Defense Forces soldiers and will be dealt by commanders accordingly".
