Opponents of last month's coup in Thailand have adopted the three-finger salute from The Hunger Games movies and books as their symbol of resistance to the military takeover. The protests so far have been relatively small. But they seem to be, well, catching fire.

Two days ago, Thailand's military declared martial law. The army chief went on television on Thursday to say that he'd changed his mind, and the army is taking control of the government.

Thailand's army imposed martial law overnight, as the country's political crisis continues to deepen. Journalist Michael Sullivan reports on the crisis from Bangkok.

The declaration by Thailand's army happened less than two weeks after the prime minister was thrown out of office by the country's Constitutional Court. The army says it needs to keep order and peace.

The political crisis in Thailand has escalated since the country's top constitutional court ousted Yingluck Shinawatra as prime minister. Amid political deadlock, there are fears of economic disaster.
