What I did : I watched the video in the link, and read through the news, also understood why they want to protest.
What I learnt :
Boycott - withdraw from commercial or social relations (a country, organization or person)
Rural - in, relating to, or characteristic of the countryside rather than the town.
Military coup - The sudden overthrow of a government by a usually small group of persons in or previously in positions of authority.
The protest is caused by the protestors and they are unhappy with the Prime Minister now , Yingluck Shinawatra. The protest cause explosions which caused 28 to be injured. He said the first explosion took place about 30 meters from Suthep Thaugsuban, the leader of the protest group, and generated a lot of smoke. The government has deployed about 20,000 security personnel throughout the city. The protestors wants to have an election and it will be held on 2 February.
