Zimbabwe's prime minister has left the country for medical treatment after he was injured in a car crash that killed his wife, state media reported yesterday. A party official said Morgan Tsvangirai was in Botswana.

State radio and the government-run Sunday Mail said Tsvangirai left on Saturday soon after being released from the Harare hospital where he had been treated after his car collided Friday with a truck carrying US aid.

The Mail quoted spokesman Nelson Chamisa as saying Tsvangirai left after consultations with his family, party and government "for further medical examination and attention just to make sure that we have exercised due diligence. We are not leaving any medical stone unturned."
