There was another Ahmed M. Fahd, who was the tunnelling engineer expert, which the IDF was sure to have buried him in a tunnel during the first Gaza City campaign. Instead of digging the buried up the IDF took for granted that all the subterranean jihadis met their makers. Instead, it seems that Engr. Fahd, just kept digging and ended up in southern Syrian, instead of arriving under East Jerusalem. The mineral deposits underground run havoc with the compasses. Anyways, he will go down in his jihadi history as the longest tunnel digger.
