A state-appointed committee Saturday publicly dismissed claims by two former policemen that they assassinated anti-apartheid activists as part of alleged police death squad activity.

The report came shortly before the expected results of a separate investigation conducted by a judge appointed by the president.The committee of investigating prosecutor Tim McNally and police Criminal Investigation Division Chief Lt. Gen. Alwyn Conradie said in their joint report that allegations by the former security policemen were "false" or "unreliable" and self-serving.

The committee was appointed by the government in October last year to probe claims by death-row prisoner Butana Almond Nofomela, who charged that while a police constable, he had been a death-squad operative who killed on orders and was convicted for such a crime.

President F.W. de Klerk in January appointed the one-man judicial commission of Justice Louis Harms to investigate 71 unsolved and apparently politically motivated murders since 1977.
