Some violence, boycotts mar Yemeni vote Yemeni men show their identity cards as they line-up outside a polling station to cast their votes in the presidential election in Sanaa, Yemen on February 21, 2012. The election brings an end to President Ali Abdullah Saleh's 33-year hardline rule in Yemen, the first Arab state where a revolt ended in a negotiated settlement. UPI/Mohammad Abdullah SANAA, Yemen, Feb. 21 (UPI) -- At least two security officials were killed Tuesday during presidential voting in Yemen, where turnout was mixed amid calls for a boycott, local media reported. Yemeni voters cast ballots in an election in which Vice President Abdurabu Mansur Hadi was the only name on the ballot. Yemeni voters who spoke with the independent Yemen Post said they were casting ballots for Hadi for the sake of national unity. Hadi's candidacy is part of an agreement signed by former President Ali Abdullah Saleh to step down in exchange for immunity. The United Nations objected to the immunity deal, saying anyone responsible for mass atrocities committed during an uprising last year should be held accountable. The Post notes that polling centers in Sanaa ran out of paper ballots because of high voter turnout. Elections officials said voters could cast ballots anywhere, however, because of security concerns throughout the country. Rights activists who spoke with the newspaper said there were clashes among revolutionary groups in southern Yemen. Very few people southern regions of the country turned out to vote because of a call for a boycott, the newspaper added. Yemeni clerics issued a religious edict Monday saying Yemenis were obligated to take part in the presidential vote. Saleh, in a farewell address published by the official Saba news agency, vowed to remain a loyal Yemeni citizen "performing my duty and my role in serving the country and its just issues through the ruling General People's Congress."
