Voting is underway in Myanmar's first election in 20 years. The election was called by the military, which has ruled Myanmar for almost 50 years. More than 29 million people are eligible to vote and candidates supporting the military are expected to win most seats. The election is being boycotted by the main opposition party, the National League for Democracy, whose leader Aung San Suu Kyi remains under house arrest. In the commercial hub of Rangoon, armed riot police stood guard at near-empty polling booths, or patrolled streets in convoys of military trucks. It is part of a clampdown that includes bans on foreign media and on outside election monitors. The election is the first since 1990, when pro-democracy candidates won by a landslide, a result ignored by the military junta.
