Zimbabwe's President Robert Mugabe has freed three men who were jailed for murder and sabotage as they battled South Africa's anti-apartheid African National Congress in 1988.

Zimbabwean state media reports the president pardoned the Zimbabwean nationals on humanitarian grounds.

The three (Kevin Woods, Michael Smith and Phillip Conjwayo) were sentenced for the murder of a Zimbabwean driver they hired to deliver a bomb to a house owned by the African National Congress.

The bomb detonated and killed the driver before he reached the destination.

South Africa's apartheid government granted the men citizenship after the crime.
