Underground Kassam launching pads big enough to hold katyusha rockets were discoverd by IDF forces operating in northern Gaza early Thursday. Taking advantage of the breach in the Rafah border wall, Hamas has wasted no time in using the recent weeks to boost its weapons and explosives supplies, as well as receive training and instructions from foreign operatives who slipped into Gaza from Egypt after the Rafah border wall was blown up. Pictures released by the IDF Spokesman's office on Thursday evening show two underground rocket silos a meter in diameter and two meters deep, big enough the army says to hold a Kassam or Grad model katyusha rocket that can be launched by remote control. 02/10/08
