Thousands of pro-democracy protesters are rallying in the streets of Thailand's capital Bangkok to demand democratic reforms. The student-led demonstrations are calling for the prime minister's resignation and changes in tough laws against criticizing the monarchy. Organizers say tens of thousands have turned out. That would make it the biggest protest since a 2014 coup when now-prime minister Prayuth Chan-ocha took power. Authorities have warned against holding demonstrations amid fears that the coronavirus could spread rapidly among participants.
