Wie üblich gibt es in Israel von zwei Leuten drei divergierende Schilderungen.
Ich halte die von Al Jazeera am plausibelsten, Auszug:

"David Chater, Al Jazeera's correspondent reporting from the scene on Tuesday, said another account of what happened contrasted with Israel's version of events.

Ahmed Abu Megteg, whose children and wife were killed in the explosion, told Al Jazeera there was no fighting in the area.

"I did not see any fighters, There were no fighters around here ... no fighting, neither from the Arabs or the Israelis," he said."
