Outraged at the turmoil in Zimbabwe, the UN Security Council declared Monday that a fair presidential vote is impossible because of the "campaign of violence" waged by President Robert Mugabe's government. The 15-nation council unanimously said it "condemns the campaign of violence against the political opposition ahead of the second round of presidential elections," which has resulted in the killing of scores of opposition activists and other Zimbabweans. The non-binding presidential statement was the council's first formal action on Zimbabwe's political and humanitarian crises. Council members also agreed that the violence and restrictions on opposition activists imposed by the government of President Robert Mugabe "have made it impossible for a free and fair election to take place" on Friday. The 84-year-old Mugabe and UN Zimbabwean Ambassador Boniface Chidyausiku pledged to press ahead with Friday's vote, despite the international criticism and the lack of opposition. Zimbabwe's opposition leader, Morgan Tsvangirai, fled to the Dutch Embassy in Harare on Monday after pulling out of the presidential runoff. A police raid also took away 60 people from his party's headquarters. He said the election was rigged and his supporters face too much violence for him to keep running. He won the first round of voting on March 29, but lacked an outright majority against Mugabe. "There has been too much violence, too much intimidation," UN Secretary General Ban Ki-Moon told a brief news conference, and a runoff "would only deepen divisions within the country and produce a result that cannot be credible." Ban said he was working with South Africa and the African Union to find a solution. Dumisani Kumalo, South Africa's ambassador to the UN, told reporters that it should be left up to the Zimbabweans to decide whether to delay Friday's voting or to revert to the earlier result and consider Tsvangirai the interim president. Most of the council's negotiations were conducted privately. Members met openly for less than a half-hour to get an update on what is happening in Zimbabwe from UN Undersecretary-General for Political Affairs B. Lynn Pascoe. He said ample evidence shows Mugabe's government is waging a "widespread campaign of retaliation and threat" and spreading "fear, hostility and attacks" against its opponents. Mugabe's government is no longer capable of holding a legitimate election, Pascoe told the council, and Mugabe's plan to push ahead with a runoff Friday "would only increase divisions and produce discredited results." US Ambassador Zalmay Khalilzad, this month's council president, read aloud the council's statement on Zimbabwe. Though non-binding, it serves as a warning to Mugabe that he runs the risk of incurring a more serious, binding council resolution if he does proceed with the election. Already, tens of thousands of Zimbabweans have been uprooted from their homes and 85 people have died in election violence, human rights groups say. Tsvangirai has repeatedly been detained by police and contended with warnings of a state-sponsored assassination plot. His top deputy was arrested on treason charges that carry the death penalty. The US, Britain, France and other Western powers tried but failed to include language asserting that Tsvangirai should be considered the legitimate president, until another fair election can be held. They faced opposition mainly from South Africa and China, Zimbabwe's biggest trading partners, and from Russia, which had previously opposed discussions on Zimbabwe. The all-day discussions on the various drafts extended into the evening. Khalilzad, speaking for the US, also accused the Mugabe's government of "criminally" blocking humanitarian aid, echoing the condemnatory statements of US and British leaders Monday. "The government cannot be legitimate," Khalilzad told reporters. "The result of the (Mugabe) government policies is the economy is in shambles; millions need help to survive; and now the government is criminally, in my view, is impeding assistance to those who are in need."
