'' Biti said Susan Tsvangirai had given support and guidance to her husband , the longtime opposition leader and head of MDC . `` As a result , we must take her passing on as an inspiration and must stop feeling pity for ourselves , '' Biti said , the MDC statement reported . The couple was traveling Friday from Harare to their rural home in Buhera when a truck collided with their vehicle , killing Susan Tsvangirai . The prime minister suffered minor injuries in the wreck , which occurred along a busy two-lane highway . Mark Weinberg , a spokesman for the U.S. Embassy in Harare , told CNN the truck belonged to a U.S. Agency for International Development partner who delivers medical supplies as part of a U.S.-British program . Edwin Tsvangirai , the prime minister 's eldest son , also spoke Tuesday to those gathered at the stadium , and said he saw the president differently after hearing Mugabe 's words at the church service . `` I would like to thank the president of Zimbabwe for his words today that made me change my understanding of him , '' he said . Mugabe said the government will provide a state-assisted funeral for Susan Tsvangirai , who will be buried in Buhera on Wednesday . Some people traveled long distances to attend the stadium service . Marriam Garwe said she traveled 200 kilometers ( 124 miles ) to be there . `` I want to pay my last respects to Mrs. Tsvangirai , '' said Garwe , 43 , who is from Mutoko . `` I am sad that she died before Mr. Tsvangirai is the president . '' Members of the MDC initially said that the prime minister believed Friday 's crash was an assassination attempt . Tsvangirai dismissed those assertions on Monday . `` When something like that happens there is speculation , but I want to assure you , if it was foul play it is one in a thousand , '' he said after returning home from neighboring Botswana . `` It was an accident that unfortunately took her life . '' Watch Tsvangirai say there was 'no foul play ' » . After the crash , Biti said police should have provided better security for Tsvangirai . The wreck might not have happened , he said , if a police escort had been on hand . Tsvangirai has long been a leading opposition figure in Zimbabwe . His agreement to join the coalition government with Mugabe last month seemed to resolve an impasse created by the disputed presidential election between Mugabe and Tsvangirai last year . Tsvangirai received the most votes in the March 2008 election , but he fell short of the 50 percent required to avoid a runoff . He withdrew as a candidate in the runoff , citing political violence and intimidation targeting his supporters . Negotiations between the two sides culminated in the power-sharing agreement..
