Zimbabwe opposition contests run-off
Zimbabwe\'s opposition Movement for Democratic Change says it will announce on Monday whether the party will withdraw from the June 27 presidential run-off.
MDC leader Morgan Tsvangirai is said to be under pressure to pull out in view of escalating poll-related violence.
The MDC says dozens of its supporters have been killed but President Robert Mugabe has blamed the MDC for the violence.
According to correspondents, a withdrawal threat could be a move to pressure the international community to ensure a fair vote.
