Thousands of anti-government protesters filled Bangkok's Ratchaprasong intersection on Sunday, calling for Prime Minister Prayut Chan-o-cha to step down.
The shopping area was transformed once again into a rally site by student-led protesters seeking to end the military’s longstanding control of Thai politics.
The rally started slowly, but gathered pace as a second stage was set up.
Jatupat Boonpattararaksa of the Dao Din group said the Ratchaprasong rally was to send a clear signal that Prayut’s time as leader of Thailand was over.
The rally came after the prime minister refused to heed the protesters’ Saturday deadline to quit before Parliament holds a special session on Monday and Tuesday to find a way out of the political conflict.
Mr Jatupat said he had little hope that the crisis could be resolved in Parliament, and protesters would continue their peaceful demonstrations.
