Al Jazeera's legal team alongside international legal experts will prepare a file on the killing of Abu Akleh to refer it to the ICC.
The Palestinian Authority's attorney general said on Thursday that its investigation shows an Israeli soldier shot Abu Akleh in a targeted killing in Jenin on 11 May.
The bullet that killed the journalist was a 5.56 mm round with a steel component used by NATO forces, he said. He reiterated that the PA will not hand the bullet over to Israel.
The death of Abu Akleh, a much-loved media icon who became a household name during the second Palestinian intifada and helped establish Al Jazeera as a major international network, was received with shock and outrage across the world.
