Thailand's anti-government red-shirts on Saturday started a new mass rally on Bangkok streets in a latest move to pressure the Prime Minister to dissolve the Lower House of parliament.

The mass protest started at about 10:20 a.m. as they gradually moved from their main rally site Phan Fah Bridge in the center of capital Bangkok.

They have organized their rally in two separate groups as the foot march is heading to Rathchprasong Intersection, and the car caravan is moving to Vibhavadhi Road.

The red-shirts and the government have had different views on the timeframe for the House dissolution.

The red-shirts have insisted that the House be dissolved by Prime Minister Abhisit Vejjajiva within 15 days and it will be the only solution to the country's ongoing political conflict.

However, Prime Minister Abhisit has proposed that it could be possible to dissolve the lower House by the end of the year.
