On the second day of demonstrations in Bangkok, about 1,000 protesters broke into Thailand's Finance Ministry while tens of thousands marched in the streets. The demonstrations were sparked by a controversial bill that would allow Prime Minister Yingluck Shinawatra's brother Thaksin Shinawatra to return to Thailand without serving a jail sentence for corruption. 

The antigovernment protesters, who were led by a former opposition Democratic Party lawmaker, marched at military headquarters, television stations and government buildings, according to a report from the Associated Press.

Government supporters also held a rally Sunday.

According to one protest leader, the demonstrations were supposed to be peaceful with individuals "blowing whistles and handing out flowers."

"We have stood by silently while her [Prime Minister Yingluck Shinawatra's] brother calls the shots and she runs the country into the ground with loss-making policies," one protester told Reuters
