BANGKOK, Dec 1 -- Violence erupted in Bangkok Saturday night between supporters and opponents of the government, leaving one dead and at least five injured.

Several rounds of gunshots and what sounds like an explosion were heard near the Ramkhamhaeng university on the eastern outskirt of the capital city.

A small street nearby was reportedly seen on huge fire. Clashes broke out between a group of anti-government protesters, including many students from the university identified as members of the Students' Network, and pro-government red-shirts who were rallying at the nearby Rajamangala Stadium.

An estimated 70,000 red shirts showed up Saturday at the stadium to voice their support for the government. Some of them were confronted by the protesters when trying to make their way into the stadium. The victim, identified by police as a 21-year-old student, was fatally shot at the back and the bullet pierced through his lung.

He was later pronounced dead at the hospital. It remains unclear who fired the gun shots. Piya Uthayo, the spokesman of the Center for Administration of Peace and Order, a special agency under the Royal Thai Police, confirmed that one person was fatally shot and died at hospital.

He said five others people were injured in the clashes between the students and red shirts. Some local reports put the number of injured at 11.

According to the Bangkok Post, a 29-year-old Cambodian worker and two university students were among those taken to hospital with gunshot wounds.

The worker apparently was a bystander and was shot in the back by a stray bullet. The prolonged anti-government movement in Thailand, which has triggered the biggest street protest since 2010, demands to uproot the so-called "Thaksin's regime," allegedly carried out by Prime Minister Yingluck Shinawatra, sister of the deposed former leader.
