Anti-government protestors demand Thai gov't dissolve Parliament

Tens of thousands of anti-government protesters have gathered in Bangkok, in a massive show of force.

They have given the government an ultimatum to dissolve Parliament or face mass marches in the city. The protestors, known as "red-shirts" have promised they will not use violence.

Around 50 thousand protesters from Thailand's rural areas have arrived in several parts of Bangkok, ahead of the main rally on Sunday. They are supporters of the United front for Democracy against Dictatorship, known as the UDD.
