The Israel Defence Forces knew about the attack which targeted an Egyptian army post on the border between Egypt and the Gaza Strip, and evacuated an outpost close to the area where the attack took place in advance of the incident. The IDF's southern area commander was involved in taking the decision to evacuate army personnel.
According to reports on Hebrew Radio, intelligence warning about Sunday's attack was received last Friday; this pushed the IDF to take a number of preventive measures a few hours before the bombings. The moves included ordering all Israeli tourists and nationals to leave Sinai and the evacuation of an Israeli military outpost near the attack site.
The radio reports claim that the IDF noticed a small Egyptian armoured vehicle about two kilometres from the border which started to weave its way around concrete barriers before it was fired upon by the Israeli soldiers. Nevertheless, the vehicle managed to make its way towards the Karam Abu Salem crossing point where heavy machine guns were used against it. It is alleged that the focus was on a small cart which apparently contained high explosives and exploded as soon as it was targeted by the Israelis.
