Soviet security agents escort one of a gang of Soviet hijackers onto a plane in Tel Aviv destined for the Soviet Union. Israeli authorities extradited four men and a woman Saturday at the USSR's request. The four men arrived in Moscow Sunday, ending a three-day drama in which the armed gang kidnapped 30 schoolchildren and then flew to Israel to escape Soviet justice. The four hijackers landed at Moscow's Sheremetyevo airport aboard two Aeroflot planes. A woman, who was earlier identified as a gang member, was a hostage, according to Tass news agency.
