Zimbabwean opposition leader Morgan Tsvangirai has urged the United Nations and African Union to intervene in the crisis over his country's elections. He told UN Secretary General Ban Ki-moon that he felt African efforts to obtain the release of results had made "no progress", a UN statement says. Mr Tsvangirai, head of the Movement for Democratic Change, believes he defeated President Robert Mugabe in the polls. Video has emerged of MDC supporters being beaten up since the vote. Human rights groups say they have found camps where people are being tortured for having voted "the wrong way". The government denies such allegations. A recount in 23 out of 210 parliamentary seats which had been due to end on Monday was delayed for an unknown period. The MDC has rejected the recount as illegal and insists it beat Mr Mugabe's Zanu-PF party outright in the 29 March parliamentary and presidential polls.
