However, the footage contradicted Israeli claims and presented new evidence that the vehicles involved in the attack were clearly marked and had their emergency lights on.
The video was captured by one of the medics who was killed in the attack and was found among the 15 medics buried in a mass grave in Gaza.
The Israeli army did not comment on the newly released footage.
The Palestine Red Crescent Society had announced the discovery of 14 bodies following the Israeli attack. The victims included eight Red Crescent workers, five Civil Defense personnel, and a UN agency staff member.
It came days after the Palestinian Civil Defense said it recovered the body of a team member killed by Israeli forces, bringing the number of deaths from the attack to 15.
