The British foreign office has confirmed that the truck that hit the car of Zimbabwe Prime Minister Morgan Tsvangirai on Friday belonged to an AIDS project jointly funded by the U.S. and Great Britain.
A foreign office spokeswoman said Saturday, "All indications are that this was a genuine accident."
The prime minister's car collided with a truck south of the capital, Harare. His wife died in the accident.
Mr. Tsvangirai has flown to Botswana where he will recuperate and rest after his hospitalization following the accident.
Sources close to Mr. Tsvangirai told reporters Saturday the prime minister is exhausted and needs time to rest.
Zimbabwean finance minister and MDC leader Tendai Biti said Saturday a police escort could have prevented the car accident.
The MDC secretary-general said that while police are investigating the crash, his party will conduct its own probe.
Zimbabwe's president, Robert Mugabe, visited the the prime minister, a long-time bitter political rival, while he was in the hospital.
Tsvangirai's wife, Susan, was 50 years old. They have six children.
Mr. Mugabe and Mr. Tsvangirai joined forces in a power-sharing government last month under intense pressure from regional leaders to end the nation's political and economic crisis following violence-marred elections last year.
