Zimbabwe's main opposition party says authorities have confiscated travel documents from its leader and other officials ahead of a regional summit. The Movement for Democratic Change (MDC) said the documents were taken at the airport in the capital, Harare. MDC leaders were due to travel to South Africa this weekend after power-sharing talks in Zimbabwe were adjourned. The MDC has been negotiating with President Robert Mugabe in efforts to end Zimbabwe's post-election crisis. The BBC's Jonah Fisher in Johannesburg says MDC leader Morgan Tsvangirai and two senior colleagues were planning to fly to South Africa for talks with President Thabo Mbeki, who has been the chief mediator at the negotiations. Speaking from Harare airport, MDC General Secretary Tendai Biti said this incident showed that the talks with Mr Mugabe's Zanu-PF party were a farce and a sham. "We can't travel without passports. There's no point. In any case the plane has left and Tsvangirai has already gone back. He has no patience for this," Mr Biti is quoted by Reuters news agency as saying. According to Mr Biti, the MDC delegation were also planning to attend a summit of the Southern African Development Community (Sadc) in Johannesburg this weekend at which Zimbabwe is expected to be top of the agenda. An official from Zanu-PF was unable to immediately comment, our reporter says. On Wednesday, Mr Tsvangirai said he remained committed to discussing power-sharing after talks with the ruling Zanu-PF were adjourned the night before. Source: BBC
