Over 50 percent of Sderot residents do not have reinforced security rooms in their homes, Army Radio reported Monday. A survey conducted by the city's engineering department discovered that Sderot was short of 3,113 security rooms. According to MK Shai Hermesh [Kadima], 4,500 of such rooms are needed in the area surrounding the West Bank. Hermesh conditioned his backing of the government budget with the erection of these rooms. According to him, permission to execute plans to start building the rooms had yet to be given, despite knowledge of how many were needed.
