RWANDA . . . A HALF-BILLION IN U.S. AID

President Clinton said he'll ask Congress for $320 million more in aid for Rwanda's dying refugees -- bringing the U.S. contribution up to almost $500,000. Clinton's also set to send 200 U.S. troops to the Rwandan capital to set up an operations base at the airport. The president said the American humanitarian effort won't cease "until the dying stops and the refugees have returned." Two thousand refugees die every day. Administration officials said the operation could create a corridor of waystations to help refugees returning from Zaire, if the first two weeks go well.
