A classified internal military video presentation showing previously unseen footage of a terrorist attack near the Zikim base on July 8, has found its way to Arabic websites. The IDF is investigating how this happened.

The attack was mounted by five Hamas commando terrorists who infiltrated into Israel through the sea on the first day of Operation Protective Edge.

IDF female lookouts identified the terrorists and alerted the forces that eliminated two of them. The IDF forces then combed the area, located three more terrorists, and killed them as well.

The presentation shows one of the terrorists placing an explosive charge on a tank. The explosive then blows up. Terrorists are also seen hurling an explosive charge at a tank.

IDF sources said that the leak is a serious breach of secrecy and that "it will be investigated and dealt with properly – not through the media.”
