Greeks were voting Sunday for the second time in six weeks. The last opinion polls published before a two-week pre-election ban showed the Syriza party of Alexis Tsipras running neck-and-neck with the New Democracy party of Antonis Samaras. But no party is likely to win enough votes to form a government on its own, meaning a coalition will have to be formed to avoid yet another election, according to a report of the Associated Press. Nearly 10 million people are eligible to vote in the country of about 11 million people. Polls close at 7pm (1600 GMT), with official results expected a few hours later.
