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.
