The IDF has launched high-level probes into a number of its attacks against civilian targets in the Gaza Strip, including two United Nations facilities and a hospital, a top defense official announced on Saturday. Angry UN officials have called for an investigation into whether Israel has committed war crimes. One case under investigation is what appeared to be an attack Thursday on the UN's main compound in the Gaza Strip which sparked a huge blaze that destroyed some of the humanitarian supplies Israel had allowed into the Gaza Strip. According to the initial probe, IDF troops came under intense anti-tank fire by a group of Hamas gunmen positioned next to the compound. The IDF returned fire and hit a fuel tanker parked next to the compound as well. The fuel spread into the compound and set the warehouse on fire. In response, the IDF allowed five fire trucks to enter the Gaza Strip to participate in efforts to extinguish the blaze.
