Tens of thousands of pro- and anti-government demonstrators massed in rival rallies in Bangkok, Thailand, on November 24.

AFP reports that more than 100,000 opponents gathered in the city's historic centre, calling for Prime Minister Yingluck Shinawatra’s government to be dissolved.

At the same time, thousands of pro-government "Red Shirts" held a rally at a suburban football stadium in support of Yingluck.

Police said they were preparing for opposition supporters to march on parliament and key government buildings on November 24 or 25, despite special security laws being enforced in sensitive zones.

Bangkok has already faced weeks of opposition-backed rallies sparked by an amnesty bill that could have allowed the return of former premier Thaksin Shinawatra.

The bill was rejected by the senate, but protesters have remained on the streets to try to topple the government.-VNA
