BANGKOK - Thai coup leader General Prayuth Chan-ocha said on Monday he had been formally endorsed by the king as head of a military council that will run the country, and warned he would use force if political protests flared up again.
He did not set a timeframe for how long the army would stay in power, although he said he hoped to hold elections soon.
Gen Prayuth seized power on May 22, saying the army would restore order after nearly seven months of sometimes deadly street demonstrations. The military has since taken into custody of scores of politicians, activists, academics and others.
"Will we go back to where we were before? If you want to do that, I will need to use force and impose the law strictly," Gen Prayuth said in a statement he read on television. "You will have to forgive any tough measures as they are necessary."
The royal endorsement is a significant formality in Thailand, where the monarchy is the most important institution.
Gen Prayuth's address is likely to provoke conflicting reaction in a country polarised by nearly a decade of rivalry between the royalist establishment, of which Gen Prayuth is a member, and Thaksin Shinawatra, a populist tycoon who broke the political mould.
Gen Prayuth, wearing a formal white dress uniform, said he would set up a council of advisers but gave no details on the form of the new government that will run the country under his military junta, the National Council for Peace and Order.
"The country needs a prime minister. If we go back and look at the past there is a way to do this but there might be some changes to the process in order to create legitimacy," he said.
The military ousted the remnants of a government that had been led by Prime Minister Yingluck Shinawatra, Thaksin's sister, until she was removed by a court on May 7 for abuse of power.
It has taken over with a heavy hand, throwing out the constitution, dissolving the Senate and censoring the media. Anyone who insults the monarchy or violates the military's orders will be tried in a military court.
Despite warnings, small crowds of people voicing opposition to the coup have been gathering in Bangkok as well as in the north and northeast, strongholds of the ousted government.
About 1,000 people thronged around Victory Monument, a central Bangkok hub, on Sunday, occasionally confronting lines of soldiers with riot shields, but there have been no clashes.
The army has allowed Yingluck to go home, although she remains under military supervision, said a senior military official who declined to be identified. "She is free to come and go as she pleases but will have to inform us as a sign of mutual respect and we will have soldiers guarding her home," the officer said on Sunday.
Suthep Thaugsuban, who led the Bangkok protests that undermined Yingluck's government from last November, was released from army custody on Monday but taken with 12 associates to the Attorney General's office. Suthep faces a charge of insurrection relating to the protests but was granted bail, said a member of his legal team.
