A leader of Zimbabwe's main opposition party says the country has reached a critical stage that could see the end of the rule of President Robert Mugabe.
The head of the Movement for Democratic Change party, Morgan Tsvangirai, said in a British television (BBC) interview Sunday that the situation in Zimbabwe has reached a tipping point.
His comments came as a party spokesman, Nelson Chamisa, was allegedly beaten at the Harare International Airport Sunday and prevented from leaving.
Two other party activists, who along with Tsvangirai were allegedly beaten by police stopping an opposition meeting last Sunday, were prevented from going to South Africa on Saturday to receive medical treatment.
Tsvangirai, who was seriously injured in the crackdown, has vowed to continue fighting against the government of President Mugabe until democratic change comes to Zimbabwe.
The African Union has called on Zimbabwe to show respect for human rights.
