There's now also a report of a fourth attack north of Eilat:
An additional shooting attack took place Thursday evening north of Eilat, in which one person was injured. Army forces, police and ambulances were seen rushing toward the location of the attack and IDF helicopters were hovering overhead.[...]This might be a side-effect of the so-called "Arab spring", and it is definitely dangerous.
IDF forces were still searching the area around Eilat and the Egyptian border out of concern that there may be terrorists still in the area. Sources said that it is possible that there were as many 20 terrorist in the area, both in Israel and on the Egyptian side of the border.
They added that there may be another terrorist cell hiding in the area. IDF and special police counter-terrorist forces killed seven terrorists during the three earlier attacks.
At a press conference Thursday evening, OC Southern Command Maj.-Gen. Tal Russo said that security forces had been on high alert for terror attacks coming from Sinai to Israel.
