Thailand's military coup is a sharp turnaround for a country that had been hailed as one of Southeast Asia's most promising democracies.
The army chief, General Sondhi Boonyaratglin signed a statement saying he had seized power from embattled Prime Minister Thaksin Shinawatra, who was facing increasing pressure to resign over corruption allegations.
Following are the approximate local times since Tuesday evening of key developments in the coup:
