Military sources estimated that the explosive device may have been activated by a remote control system. "Ever since the IDF pulled out of the Gaza Strip, explosive devices have been considered one of the main threats," a military source said. "The forces have uncovered hundreds of devices on the border fence and have hit the terrorists related to these attempts." 'If we fail to operate, we'll see terror attacks in Israel' Shortly after the incident, several mortar shells were fired at agricultural fields in Kibbutz Ein Hashlosha. There were no injuries, but the farmers in the area were forced to halt their work. IDF sources estimated that this was not an attempt to carry out a combined terror attack, but said that Thursday's incident demonstrated the terror threats in the Gaza Strip.

Over the past few months, ahead of a possible wide-scale ground operation in Gaza, the defense establishment has been monitoring the strengthening of militants in the Strip. Large amounts of weapons are flowing freely through the Sinai desert and the Philadelphi route. Two IDF soldiers, Staff Sergeant Dror Asulin and Eran Dan-Gur, were killed last week during Operation Warm Winter in the northern Gaza Strip. The forces operating in the Strip reported encountering fighters with large amounts of weapons, determination and fighting spirit. Diplomatic sources in Jerusalem noted Wednesday that the wide-scale operation in the Strip was being delayed for now in order to give Egypt an opportunity to stop Hamas from getting stronger, and perhaps reclose the breached Rafah border and enforce the control of the crossings.
