The US ambassador to South Africa has accused the country of supplying weapons to Russia despite its professed neutrality in the war in Ukraine.
Reuben Brigety claimed that a Russian ship was loaded with ammunition and arms in Cape Town last December.
President Cyril Ramaphosa’s office said it was disappointed by the claims and said no evidence has been provided to support them.
The country has maintained claims of neutrality in the invasion of Ukraine.
Mr Brigety said at a media briefing in Pretoria on Thursday that Washington had concerns about the country’s stated non-aligned stance on the conflict.
He referred to the docking of a cargo ship in the Simon’s Town naval base between 6 and 8 December last year which he was “confident” uploaded weapons and ammunition “as it made its way back to Russia”.
The presence of the ship, the Lady R, had seemed curious at the time and raised questions from some local politicians.
“The arming of the Russians is extremely serious, and we do not consider this issue to be resolved,” Mr Brigety said, in a damning accusation that seems to have caught South Africa’s officials off guard.
In the wake of the allegations, the South African government announced the establishment of an independent inquiry led by a retired judge, a spokesman for the president’s office said.
The US has been critical for months about South Africa’s continued cosy relationship with Russia.
State Department deputy spokesman Vedant Patel told journalists on Thursday that the US had previously raised concerns about the Lady R with numerous South African officials.
He said the US would speak out against “any country taking steps to support Russia’s illegal and brutal war in Ukraine”, but would not say whether there would be any repercussions for South Africa if the claims proved to be true.
Washington has also expressed concerns about South Africa’s participation in military exercises with Russia and China during the anniversary of the invasion of Ukraine.
meant that Pretoria would have to detain him on arrival.
In response, last month Mr Ramaphosa said the ANC had decided that South Africa should quit the ICC, before backtracking hours later citing what his office called a communications “error”.
Historically, South Africa had a thriving arms industry, selling weapons to countries across the continent. The scale of that arms power to date is currently not known.
South Africa’s authorities have been less than pleased with the accusation from the US ambassador, saying the matter should have been handled through proper diplomatic channels.
It is not enough for the envoy to simply claim the existence of the intelligence and there will be an expectation from many in South Africa for the US to provide evidence of its claim.
This is a hang-up of claims once made by the US of weapons of mass destruction, which led to the invasion of Iraq some years ago.
