In Thailand, the government cracked down on pro-democracy protesters Thursday, imposing a state of emergency in an effort to quell the ongoing student-led movement to remove Prime Minister Prayut Chan-o-cha. Two protest leaders and at least 20 pro-democracy activists were arrested early Thursday morning in Bangkok after tens of thousands gathered outside the prime minister’s office. The state of emergency bans gatherings of more than five people and prohibits news media that is a so-called threat to national security.
