Sri Lankans Vote in Post-Civil War Presidential Election More than 14 million eligible voters are choosing between President Mahinda Rajapaksa and former army chief Sarath Fonseka VOA News 25 January 2010 Rajapaksa supporters with anti-Fonseka placards at rally, 24 Jan 2010 Photo: VOA Rajapaksa supporters with anti-Fonseka placards at rally, 24 Jan 2010 Sri Lankans are voting Tuesday in the country's first post-civil war presidential elections, contested by the two architects of last May's military victory over the Tamil Tiger rebels. More than 14 million eligible voters are choosing between President Mahinda Rajapaksa and former army chief Sarath Fonseka, former allies who have turned into irreconcilable enemies. The two have traded accusations of war crimes, corruption and incompetence. Full preliminary results are expected to be announced Wednesday. Sri Lanka's Foreign Minister Rohitha Bogollagama warned Monday that up to 800 army deserters, most of them allied with Fonseka, are poised to disrupt the elections. Fonseka, meanwhile, claimed that five battalions deployed in the capital, Colombo, are a sign he and other opposition leaders could be targeted as part of a "military coup" should he win. Western diplomats expressed concern about the potential for violence by supporters of the two rivals. Several explosions were heard in the predominantly ethnic Tamil town of Jaffna in northern Sri Lanka before the polls opened Tuesday. An independent election monitoring group said at least one explosion struck the office of a ruling party activist, but no one was hurt. There are only 20 international observers in the country for the election, but more than 3,700 Sri Lankan monitors are to be stationed at polling centers.
