A blast that narrowly missed Zimbabwean President Emmerson Mnangagwa at a weekend rally in Bulawayo has claimed its first fatality, a state-run radio station reported Monday.
Those policies were cornerstones of Mugabe's near four-decade rule, but the ruling ZANU-PF says Zimbabwe is at a critical stage of its transition and needs an experienced hand like Mnangagwa at the tiller. The blast occurred at White City Stadium in Bulawayo. He has openly joked about them at rallies. He added: "I can assure you these are my normal enemies".
Mnangagwa even pledged that the attack would not derail what has been a largely peaceful election campaign so far, adding elections would go ahead on July 30 as scheduled.
The main competition will be between Mnangagwa and the main opposition Movement for Democratic Change's leader, 40-year-old Nelson Chamisa.
