BANGKOK, THAILAND: "Now the farmers are protesting (February 20) because they have not been paid for their rice. They set out to block the airport but have been blocked on the highway on the outskirts of Bangkok. We estimate 10000 farmers in a 5 km convoy." - CNN's Brad Olson. Protesters in Bangkok have been calling for months for the ouster of Prime Minister Yingluck Shinawatra, whom they allege is a puppet of her billionaire brother, the deposed, exiled former Prime Minister Thaksin Shinawatra.
