Bangkok tense as political rivals take to the streets

BANGKOK - Tens of thousands of anti-government demonstrators massed in Bangkok on Sunday, with a major rally scheduled later by their rivals, as Thailand faces its most significant political street action since bloody protests in 2010.

Organizers said 100,000 anti-government protesters had gathered by Sunday afternoon, while thousands of pro-government "Red Shirts" were expected to mobilize later at a suburban football stadium in support of Prime Minister Yingluck Shinawatra's crisis-hit administration.
