Army-imposed calm returned to Bangkok Thursday after a crackdown put an end to weeks of violent protests. But the feeling is that nerves are still raw and fighting could break out again at any moment. During the day, a few protesters still draw fire from the troops. And at night, authorities are keeping the country under control by extending the curfew for three more days in the capital and 23 other provinces. "We can immediately fix the roads," said Bangkok Governor Sukhumbhand Paribatra. "But we do not know how long it will take to fix the wounded hearts and minds of the people." For the most part, protests came to an end on Thursday a day after the Red Shirt leaders turned themselves in.
