Sri Lanka’s main opposition presidential candidate Maithripala Sirisena gestures as he leaves after casting his vote during the presidential elections at a polling station in Polonnaruwa, about 200 kilometers (124 miles) northeast of Colombo, Sri Lanka, Thursday, Jan. 8, 2015. Monitors on Thursday expressed concerns that voters are being prevented from casting their ballots in some parts of Sri Lanka in an election where President Mahinda Rajapaksa faces a fierce political battle after Sirisena, his onetime ally, suddenly defected from the ruling party to run against him.
