Tsvangirai detained in Zimbabwe
Mr Tsvangirai and President Robert Mugabe face a run-off on 27 June
Zimbabwe opposition leader Morgan Tsvangirai has been detained by police during campaigning for the country's presidential election, his party says.
A convoy carrying the Movement for Democratic Change leader was stopped at a police roadblock at 1000 GMT, party spokesman Nelson Chamisa said.
The MDC leader and his entourage were taken to a police station in the far west of the country, said Mr Chamisa.
"It appears they want to disrupt our campaign programme," he said.
It comes as Zimbabwe prepares for a run-off election between Mr Tsvangirai and President Robert Mugabe on 27 June.
