Kremlin admits it has advisers in Angola

After more than two weeks of silence, the Soviet Union acknowledged the presence of its military advisers in Angola and demanded the return of a soldier captured in a South African raid in which four Russians were killed.

The announcement, carried by Tass, the official news agency, referred to last month's raid into Angola in pursuit of black nationalist guerillas in which South Africa claimed to have captured a Soviet soldier.

Tass said Soviet citizens help Angola in various fields, including defense. Meanwhile SWAPO leader Sam Nujoma denied South African charges that Soviet troops are fighting alongside his nationalist guerillas in their war for the independence of Namibia (South West Africa).
