WASHINGTON (AP) -- The United States says it is "deeply concerned" about thousands of protesters who have occupied Thailand's airports in an anti-government campaign that marks the country's worst political crisis in decades.
He says the United States urges the protesters "to walk away from the airports peacefully."
Thailand's capital remains completely cut off from air traffic.
The protest grew out of the PAD's hatred of former Prime Minister Thaksin Shinawatra. Thaksin was ousted in a bloodless military coup in September 2006 after months of protests by the alliance.
Thaksin and his allies are being accused of corruption and abuse of power.
