Police fire tear gas on Thai parliament protesters

Thai police fired tear gas to try and disperse thousands of anti-government protesters massing outside parliament on Tuesday, local television channels reported.

Police fired off the rounds at about 6.20am after rumors circulated that authorities would break up the fresh rally, state-run Channel Nine and Channel Three reported.

Thousands of supporters of the People's Alliance for Democracy (PAD) marched to parliament late Monday, using trucks to try and seal off the building ahead of an address by the new cabinet.

Thailand's new government are due on Tuesday to deliver their first policy address to the house, but the protesters are demanding the elected administration step down.

Protesters have occupied Bangkok's main government compound since late August, but many moved to nearby parliament Monday evening after lawmakers agreed in principle to amend the constitution -- a move that the PAD opposes.

PAD leaders are demanding that the democratic elected government step down because of its links to ousted prime minister Thaksin Shinawatra.
