President Robert Mugabe faced an uncertain future for the first time in his 28-year rule of Zimbabwe, after the opposition claimed victory in last weekend's presidential race and his ruling party lost control of parliament, official results show.

Opposition leader Morgan Tsvangirai will beat President Robert Mugabe in Zimbabwe's closely-watched election, but be forced into a runoff vote in three weeks, according to a ruling party projection.

As officials began to release election results Monday, showing a split between Zimbabwe's ruling party and the opposition, accusations of President Robert Mugabe's government rigging returns to hide a loss threatened to throw the country into chaos.
