The bombs that went off in the South African township of Soweto outside Johannesburg have killed one person and left another critically injured.

No-one has so far claimed responsibility for the explosions, and the investigations are just beginning, but, South Africans already fear the country's far right is behind the blasts

All the South African police are prepared to say is that the nine blasts were caused by explosive devices.

But a pattern is already clear.

The attacks were well co-ordinated by people who probably had military training.

Rising anger

According to Martin Schonteich of the Institute for Security Studies in Pretoria that appears to point towards South Africa's small, but vociferous right wing.

The far right have had little influence since they rode into one of the nominally independent homelands just before the first truly democratic elections were held in 1994, only to turn tail when the first shots were fired.

Police are searching for clues

Since then they have been relatively quiet.

But recently anger, particularly among Afrikaners, has been growing.

After ruling the country for over 40 years, they now have no say in its destiny.

And they fear that the growing violence in Zimbabwe will spill over in South Africa - already about 100 farmers are being murdered a year in what the far right interpret as a campaign to drive them off their land.

Mr Schonteich says that the extreme right has neither the capacity nor the allies to pose a real threat to the South African Government, but believes they have the potential to create disorder and destruction on a significant scale.

Recently a group of far right whites went on trial, accused of plotting to overthrow the state.

None of this is in any way conclusive evidence of who is behind the bombings, but suspicion points in their direction.
