From The NY Sun:
The ruins of two large synagogues in evacuated Jewish communities of the Gaza Strip have been transformed into military bases used by palestinian Arab groups to fire rockets at Israeli cities, according to a senior leader of a Gaza militant group. When Israel withdrew from the Gaza in August, 2005, it left intact 20 synagogues of the Gush Katif Jewish communities following an Israeli Cabinet decision against demolishing the structures. Immediately after the Israeli evacuation was completed, palestinian Arabs destroyed most of the Gaza synagogues.
