Baby Rouh has died after just a few days of life, the doctor who was caring for her said on Friday
One Palestinian official said Shireen Abu Akleh had been "assassinated" by Israeli forces while reporting on a raid in the city of Jenin, which has seen intensified army raids in recent weeks as violence has surged.
The Palestinian health ministry confirmed Abu Akleh's death and said a second reporter, Ali Samodi, had been wounded.
In a statement, the military said its troops had shot back after coming under "massive fire" in Jenin and that "there is a possibility, now being looked into, that reporters were hit - possibly by shoots fired by Palestinian gunmen".
