London - The British government said late Saturday it believed the automobile crash that injured Zimbabwean Prime Minister Morgan Tsvangirai and killed his wife Susan was indeed an accident and not a politically motivated attack as some have alleged.

The truck that collided with Tsvangirai's car belonged to a British-American organization, the British foreign ministry said in London.

The evidence points to an accident, a spokeswoman said.

In a statement released in South Africa Saturday, Tsvangirai's party, the Movement for Democratic Change (MDC) described the crash as a "perfect organised hit".

In Zimbabwe, leading MDC members stopped short of such a direct accusation, but said they were making their own investigations, and accused the government of failing to provide the protection of a police escort for Tsvangirai.

Tsvangirai survived the Friday crash with minor injuries after his vehicle was hit by an oncoming truck and overturned, but his wife of 31 years, Susan, was killed. (dpa)
