The Palestinian attorney general has blamed Israel for deliberately killing veteran al-Jazeera reporter Shireen Abu Akleh.
The reporter was killed a fortnight ago during an Israeli military operation in Jenin in the northern West Bank.
Her death and police violence at her funeral in Jerusalem caused international consternation.
Attorney General Akram Chatib told journalists that an investigation into the fatal bullet had revealed that it had been fired by a sniper with a Ruger rifle.
The bullet had come from the direction of the Israeli soldiers.
Further bullet holes in a tree showed that the upper body of the 51-year-old woman, who was well-known in the Arab world, had been targeted.
This showed a clear intention to kill, Chatib said.
According to the Israeli army, on the other hand, it is not clear from where the fatal shot came.
It reported fierce firefights with Palestinian militants in Jenin.
The Palestinian leadership had rejected Israel's request for a joint investigation.
Since March, 18 people have been killed in a wave of violence in Israel, and an Israeli security guard and a soldier were also shot dead by Palestinians in the West Bank.
Several attackers came from the Jenin area.
The town is considered a stronghold of Palestinian militants.
For weeks, the Israeli army has been conducting raids there and in other parts of the West Bank.
According to the Palestinian Ministry of Health, more than 30 Palestinians have been killed since the end of March.
Some of them were killed in military operations but also in their own attacks or in clashes with the army.
