Three Palestinians were killed Thursday night after they were struck by IAF-fired missiles as they tried planting an explosive device along the Gaza Strip security fence near the Kissufim crossing. The three were spotted by an IDF infantry unit that had laid an ambush on the Israeli side of the Gaza fence. The unit transmitted the coordinates of the terror cell to the IAF and an aircraft, already in the air, fired the missiles. The three were killed instantly. Palestinians frequently try to plant bombs next to the security fence to target military forces that patrol nearby. Meanwhile, an IDF soldier was lightly wounded from gunfire during an IDF operation in Nablus overnight Thursday. The soldier was evacuated from the scene for medical treatment. Also on Thursday night, IDF forces successfully prevented the firing of a Kassam rocket from the Gaza Strip. Troops identified a group of Palestinians preparing for a rocket launch and opened fire on them. There were no casualties reported as a result of the army gunfire and the rocket was not fired. Six Kassam rockets, however, were launched over the course of the night, five of which landed in open terirory in the western Negev. No one was wounded and no damage was reported.
