Zimbabwe President Emmerson Mnangagwa has cut his international trip short and is returning to home amidst widespread condemnation of the response of security forces to fuel protests in the country. Mnangagwa was expected in Davos, Switzerland this week after visting Russia, Belarus, Azerbaijan and Kazakhstan. Zimbabwe will now be represented at the World Economic Forum in Davos starting on Tuesday by Finance Minister Mthuli Ncube. Rights groups in Zimbabwe say security forces, accused of night raids at homes of suspected protesters, are now trying to track down people who have gone into hiding.
