HARARE, Zimbabwe — Zimbabwe's state election commission has acknowledged some mistakes in disputed elections last week, but says they were not enough to sway what it said was a landslide victory for President Robert Mugabe.

The panel said Thursday that nearly 305,000 people were turned away from voting and another 207,000 were "assisted voters" who needed help from polling officials to cast ballots. Previously, it reported that some voters went to the wrong polling stations, as well as other errors.

The defeated opposition leader, outgoing Prime Minister Morgan Tsvangirai, has said alleged vote-rigging was widespread.

About half of Zimbabwe's 12 million people were eligible to vote.

The African Union and a bloc of southern African nations have generally been supportive of the vote. Sharp criticism has come from non-governmental groups and Western governments.
