After truce negotiations brokered by Egypt last week and a brief humanitarian ceasefire promoted by UN Special Coordinator Robert Serry failed to bring about an agreement between the parties to stop the hostilities, the Israeli government decided to launch a ground invasion in the eastern perimeter of the Gaza Strip. Its main goal has been the destruction of dozens of tunnels that the Palestinian militias had dug underneath this area over the last few years. Some of the tunnels have offensive purposes—their exits are located on the Israeli side–though most of them are defensive, allowing the militias to move underground and avoid detection by Israel Defense Forces (IDF) drones and observation points along the security fence.
The ground offensive started right after the IDF foiled a spectacular attempt by thirteen commandos of the Izz ad-Din al-Qassam Brigades to infiltrate Israeli territory in a very similar way the Popular Resistance Committees did in June 2006 when they kidnapped the Israeli soldier Gilad Shalit. The fact that this attempt took place a few hours before the beginning of the five-hour humanitarian ceasefire that had been agreed upon through Serry's mediation, and that it was captured on camera and broadcast widely on TV and social media, made the ground invasion unavoidable. Even Israel's military intelligence experts were amazed by the degree of sophistication of the tunnel networks.
