CHRISTOPHER HEADS EAST

Secretary of State Warren Christopher today set out for Cairo to begin a five-nation drive to get Mideast peace talks back on track. Christopher is flying overnight to Cairo and is slated to continue to Israel, Saudi Arabia, Syria and Jordan, plus a Gaza visit with PLO chairman Yasser Arafat. Since Christopher last touched down in the region three months ago, the peace process has gotten bogged down by Israel's quarreling with the Palestinians, Syria and Egypt, while Israel's tentative peace deal with Jordan hit a financial snag.
