Egyptian authorities postponed announcing results of the presidential election Thursday, citing complaints of voter fraud by both candidates, CBN News reports. The Election Commission said a panel of judges would need time to examine the estimated 400 complaints before announcing the winner, possibly Saturday or Sunday. Early Monday, Muslim Brotherhood candidate Mohammed Morsi declared he had won with 52 percent of the vote, but former prime minister Ahmed Shafiq said he had won at least 51.5 percent. Shafiq claimed thousands of pre-marked ballots were delivered to at least 14 of 27 polling stations staffed by officials backing the Muslim Brotherhood, and authorities so far have arrested three polling station heads suspected of vote tampering. Meanwhile, the Brotherhood's leaders have warned that its supporters will initiate street protests if Shafiq is declared the winner.
