On 23 January 2007 (Lunar Calendar 5 December 2006) the border wall between Gaza and Egypt was blown up by disguised militants. On 23 January 2007, about two-thirds of the border walls between the Gaza Strip and Egypt, located in Rafah, were destroyed by disguised militants, and tens of thousands of Palestinians subsequently flooded into Egypt to buy food and fuel. According to witnesses, the militants began to break the border wall before dawn. Hamas officials then blocked most of the border lines, but left two gaps to allow Palestinians to freely exit. Hamas police wereining traffic. Egyptian border guards did not take any measures, security personnel and police were withdrawn from the border zone, but Egypt did not give any explanation about this.
