JERICHO - Israeli troops on Thursday demolished four villas near the ancient city of Jericho, which Israel said endangered a nearby archaeological site, sources on both sides said. An AFP correspondent at the scene said the villas, which are located in Ad-Duyuk at-Tahta northwest of the town, were owned by Palestinians living in Jerusalem and Ramallah. Locals at the scene said the villas had been demolished because they were built without a permit. A spokesman for COGAT, a unit within the Israeli defence ministry which administers the occupied West Bank, said the homes were built without permission and were endangering a nearby archaeological site.
