The May sky quickly turned black from thick smoke billowing from landmark buildings set ablaze . Finally , after hours of intense street battles , the Red Shirt leadership surrendered . The government imposed a strict curfew that barred people from going outside between 8 p.m. and 6 a.m .

He said soldiers were given the all-clear to fire if they faced a clear threat . iReport : Video sparks discussion . `` The terrorists have created further situations of violence by torching government and business buildings , '' Sansern said . `` It was therefore necessary for the police and military to put further pressure .

Witnesses reported a dozen buildings -- including a bank , a police station , a local television station and Thailand 's biggest shopping mall -- set ablaze . Hours after the large military operation got under way , soldiers took control of the park area . The Red Shirt leadership called off the protests , telling a crowd at the park that they wanted to avoid further bloodshed and wanted to turn themselves in .

'' The Red Shirt opposition members support former Prime Minister Thaksin Shinawatra , who was ousted in a bloodless 2006 military coup . They have been protesting for weeks , demanding that Abhisit dissolve parliament and call new elections . From his self-imposed exile abroad to avoid a trial on corruption charges , Thaksin released a statement Wednesday saying he was not the leader of the United Front for Democracy , the formal name of the Red Shirt opposition , and that their movement calling for new elections is not on his behalf . `` They did not demand anything for me or on my behalf . I am not UDD , '' he said . Thaksin also accused the Thai government of defaming him by saying he was the mastermind behind the violence in the country 's ongoing political crisis . `` I never approve nor agree to any use of violence , '' he said . `` I believe in peace . I love my country as much as any member of this government . I believe in peaceful and non-violent means to end conflict and reject any use of force . `` If there is any act of terrorism , it is the duty of this government to find the wrongdoer and prosecute them in the court of law . '' The violence prompted the United Nations ' top human rights official to implore anti-government protesters and government officials to resume talks . But on Wednesday in Bangkok , as bullets rang out , black plumes of smoke rose and soldiers crept forward toward a showdown , it seemed that the time for talking had passed . iReport : 7-11 at OnNut Looted/Bombed .
