His Majesty the King has acknowledged the letters sent by the National Council for Peace and Order (NCPO) about the power seizure, the junta said in a statement yesterday.
In the statement, signed by Army chief and NCPO head General Prayuth Chan-ocha, the junta said it had twice in writing on Tuesday and Thursday detailed the armed forces' movements to the Office of His Majesty's Private Secretary.
The Office responded in writing yesterday that His Majesty was aware of the developments.
The junta also said former prime minister Yingluck Shinawatra and ousted government leaders would be detained for up to one week.
In its first media briefing since Thursday's power seizure, the junta declined to specify where the detainees were being held but said they were in no danger, Agence France-Presse reported.
"They will be detained for up to one week depending on how directly they were involved [in Thailand's political turmoil]," Army spokesman Colonel Winthai Suvaree told reporters.
US cancels military exercise, visits after Thai coup
WASHINGTON - The United States has cancelled an ongoing military exercise with Thailand and planned visits by officials after the Thai army seized power in a widely condemned coup.
Thailand's army said Thursday it had taken power in a coup after months of unrest and deadly political violence, provoking an international outcry and heightening fears for the future of the Asian country and its fragile democracy.
"While we have enjoyed a long and productive military-to-military relationship with Thailand, our own democratic principles and US law require us to reconsider US military assistance and engagements," Pentagon spokesman Rear Admiral John Kirby said in a statement Saturday.
The Cooperation of Afloat Readiness and Training exercise (CARAT), which involves several hundred US Marines and sailors, began Monday and was supposed to run for a week.
The scrapped visits had been planned for June - one to Thailand by US Pacific Fleet Commander Admiral Harry Harris and another to the US Pacific Command in Hawaii by a high-ranking Thai military official.
"It is important that the Royal Thai Armed Forces end this coup and restore to the people of Thailand both the principles and the process of democratic rule, including a clear path forward to elections," Kirby said.
"We urge the Royal Thai Armed Forces to act in the best interests of their fellow citizens by ending this coup and restoring the rule of law and the freedoms assured those citizens through democratic principles." The US military has long-standing ties to Thailand's armed forces, dating back to the Korean and Vietnam wars.
Still, the Pentagon also warned of potentially more cuts.
"We will continue to review additional engagements as necessary until such time that events in Thailand no longer demand it," Kirby said.
Word of the cancellations comes on the heels of an announcement by Washington on Friday that it had suspended US$3.5 million (S$4.38 million) in military assistance to its oldest treaty-bound ally in Asia.
The US State Department meanwhile said that the United States was reviewing the rest of its aid to Thailand - which totaled US$10.5 million in 2013.
In a statement, State Department spokeswoman Marie Harf said Washington had now also called off a US government-sponsored firearms training programme for the Royal Thai Police that had been scheduled to start Monday.
"We are increasingly concerned about actions the military has taken, just a few days after it staged a coup," Harf said, pointing to the dissolution of the Senate, arrests and media restrictions.
"We again call on the military to release those detained for political reasons, end restrictions on the media and move to restore civilian rule and democracy through elections."
