Thai Police Remove Barricades
Protesters want the prime minister to step down
Thai protesters entered the government's headquarters after police removed barricades from outside both Government House and the police office.
The mood in the capital Bangkok appeared considerably calmer after the move, which followed clashes over the weekend and on Monday.
But as tensions fell, protest leader Suthep Thaugsuban vowed to fight on and remove the government.
The Thai prime minister has rejected protesters' demands that she step down.
