Ballot counting is underway in Zimbabwe after a referendum for a new constitution that would curb the powers of the president.
Results for Saturday's vote are expected to show wide support for the changes which limit the president to two five-year terms, as well as, increased parliamentary powers.
Eighty-nine-year-old President Robert Mugabe and his rival, Prime Minister Morgan Tsvangirai, both supported the draft constitution. Mr. Mugabe has ruled Zimbabwe for more than three decades, and even under the new constitution, he could remain on the job another 10 years, if re-elected.
Meanwhile Sunday, Zimbabwe police detained three senior aides to the prime minister, the latest in a clampdown of pro-democracy groups in the run-up to the referendum vote.
The three were arrested at their homes in the capital, Harare, Sunday morning. The reason for their detention is unknown.
