Bangkok chokes as pollution busting efforts falter

Bangkok, Thailand - The small park in Bangkok's Rama III district is mostly popular with runners circling its neatly trimmed garden track to the sound of birdsong. But on Thursday, they were joined by a convoy of fire trucks and half a dozen military drones, drawing dozens of curious onlookers. After an hour setting up, the drones and water cannon were pumping thick plumes of water into the empty sky above. Speakers blared warnings about the operation and instructed runners to keep their distance. The odd display was the Thai government's latest attempt at curbing the alarmingly high levels of pollution that have been plaguing the capital for weeks.
