The Palestinian Health Ministry identified the victims as Ashraf Mubaslat, Adham Mabrouka and Mohammad Dakhil, who according to Tel Aviv, were involved in attacks against the occupation forces.
The website of The Jerusalem Post reported that the car was hit by more than 80 bullets.
The source said that the dead were members of the Al Aqsa Martyrs Brigade, affiliated to the ruling Al Fatah movement.
After the attack, the militia warned that it will respond “blood for blood”.
Palestine’s Islamic Resistance Movement (Hamas) and Islamic Jihad also made similar statements.
Regional television stations showed footage of the vehicle full of bullet holes.
The official Wafa news agency reported that a fourth person was allegedly inside the car but was detained by the military.
Both the Palestinian Government and the Foreign Ministry condemned the military operation, which they described as an extrajudicial killing, and called for an international investigation.
