Flights in and out of Bangkok resumed Wednesday after anti-government protests that paralyzed the capital's international airport for more than a week ended with the peaceful ouster of the prime minister.

The first commercial flight in a week arrived in Bangkok on Wednesday as anti-government protesters ended their siege of the country's two main airports, declaring victory after Thailand's prime minister was ousted by a court ruling.

Southeast Asian countries Wednesday said they regretted that Thailand's political turmoil drove it to postpone a regional summit, with Singapore urging prompt cooperation on the world financial crisis.
