What was the cause of their protest?
Bangkok, Thailand (CNN) -- Thailand's bitter political crisis intensified Tuesday as five people were killed in clashes between
anti-government protesters and police, and the country's anti-corruption commission filed charges against the Prime Minister.
The violence erupted in the heart of Bangkok after months of protests against Prime Minister Yingluck Shinawatra that have deepened political divisions in the Southeast Asian nation.
A police officer died after he was shot in the head, and four other people -- at least two of them protesters -- were also killed, officials said.
Seventy-three people, both police officers and protesters, were wounded in the clashes Tuesday, according to the Erawan Emergency Center, a medical unit monitoring the unrest in Thailand.
