Riot police in the Thai capital have fired tear gas at protesters trying to force their way into the prime minister's office compound and Bangkok police headquarters.

Reporters saw anti-government protesters trying to rip down concrete barriers outside the Government House on Sunday. Police fired tear gas and water cannons to push them back.

Separately, police drove back another crowd of protesters at the Bangkok police headquarters.

This was the first time police have used force against protesters who have occupied government offices for the past week in a bid to topple Prime Minister Yingluck Shinawtra.
