Jerusalem officials are studying Egyptian President Hosni Mubarak\'s announcement of last night in which he opposed sending observers to Judea and Samaria. Mubarak expressed doubts as to the effectiveness of such observers and their ability to \"put a stop to the violence between Israel and the Palestinians… Without a true desire to end the killings, the observers can do nothing.\" He did not rule out a change of mind in the future, however, and dispatched his diplomatic advisor Osama al-Baz to Washington to discuss the matter.
