BANGKOK - Thai army chief Prayuth Chan-ocha summoned ousted Prime Minister Yingluck Shinawatra to a meeting on Friday, a day after he seized power in a bloodless coup and said he wanted to restore order following months of turmoil.
General Prayuth launched his coup after the rival factions refused to give ground in a struggle for power between the royalist establishment and a populist government that had raised fears of serious violence and damaged Thailand's economy.
Soldiers detained politicians from both sides when Prayuth announced the military takeover, which drew swift international condemnation, after talks he was presiding over broke down.
Leaders of pro- and anti-government protest groups were still believed to be in detention, said an opposition lawmaker who declined to be identified.
The military banned 155 people, including politicians and activists, from leaving the country. The military also censored the media, dispersed rival protesters in Bangkok and imposed a nationwide 10 p.m. to 5 a.m. curfew.
It then called Yingluck and 22 associates, including powerful relatives and ministers in her government, to a meeting at an army centre in the capital.
Yingluck is the sister of Thaksin Shinawatra, a billionaire telecommunications tycoon turned politician who won huge support among the poor but the loathing of the royalist establishment, largely over accusations of corruption and nepotism. He was ousted as premier in a military coup in 2006.
Yingluck arrived at the army facility at noon, shortly after some of her aides, a Reuters witness said. Prayuth was also present. He was expected to meet King Bhumibol Adulyadej on Friday at the royal palace in Hua Hin, south of Bangkok, to explain the army's move.
Yingluck was forced to step down as prime minister by a court on May 7 but her caretaker government, buffeted by more than six months of protests, had remained nominally in power, even after the army declared martial law on Tuesday.
The meeting could set the tone for army rule as Prayuth tries to steer the country out of crisis and fend off international criticism of the latest lurch into military rule.
Bangkok was calm and life appeared normal, although the military ordered all schools and universities to stay closed. Public transport was running after the curfew ended and morning traffic was light. Cars were moving slowly on some roads into the capital because of army checkpoints.
Regular television schedules were suspended with all stations running military announcements interspersed with footage from the army's channel.
It showed sites, now cleared, that had been taken over in and around Bangkok by political groups since anti-government protests flared in November. Other footage showed people going about their business in different parts of the country with some saying they welcomed the coup.
US Secretary of State John Kerry said there had been no justification for the coup, which would have "negative implications" for ties with its ally, especially military ones.
"The path forward for Thailand must include early elections that reflect the will of the people," Kerry said in a statement. He also called for the release of detained politicians.
There was condemnation from France, the European Union and the United Nations human rights office. Japan said the coup was regrettable, Australia said it was "gravely concerned".
Countries including Singapore and South Korea advised citizens against travel to Thailand.
Prayuth is a member of the royalist establishment generally seen as hostile to the Shinawatras, although he tried for months to keep the army out of the strife and to appear even-handed.
He enjoyed cordial relations with Yingluck after she took office following a landslide election victory in mid-2011 but is regarded warily by some Thaksin supporters.
The army chief, who is 60 and due to retire later this year, has taken over the powers of prime minister but it was not clear if he intended to stay in the position.
An undercurrent of a crisis that is dividing rich and poor is deep anxiety over the issue of royal succession.
King Bhumibol, the world's longest-reigning monarch, is 86 and spent the years from 2009 to 2013 in hospital. Crown Prince Vajiralongkorn does not command the same devotion as his father, but some Thaksin supporters have recently been making a point of their loyalty to the prince.
Market reaction muted
The anti-Thaksin protesters had demanded electoral changes that would end the Shinawatras' success at the ballot box.
Thaksin or his parties have won every election since 2001.
Thaksin's "red shirt" supporters were dismayed and angry but said they had no immediate plans for protests that they had threatened in response to any army takeover.
Those who had been protesting in Bangkok dispersed peacefully after the coup.
Protests would be a major test for Prayuth, who commands an army known to contain some Thaksin sympathisers.
In 2010, more than 90 people were killed in clashes, most when the army broke up protests against a pro-establishment government that had taken office after a pro-Thaksin administration was removed by the courts in 2008.
Weary investors have generally taken Thailand's upheavals in their stride and the baht was slightly firmer at around 32.55 per dollar. It had weakened to 32.70 in offshore trade after the coup.
The stock market was down 1.5 percent at the mid-session break after ending 0.2 percent higher on Thursday before the coup news.
Domestic investors had taken the view that the martial law imposed on Tuesday might bring some stability.
Thailand's economy contracted 2.1 percent in the first quarter of 2014 from the previous three months, largely because of the prolonged unrest, which has frightened off tourists and dented confidence, bringing fears of recession.
