The U.S. government on Sunday called for the release of Myanmar leader Aung San Suu Kyi amid a reported military coup following a disputed election, and warned of "action" unless the situation is reversed.

The United States has expressed "grave concern and alarm" regarding reports that the Myanmar military has detained civilian government leaders, and called on the military to release the officials and "respect the will of the people" as expressed in democratic elections on Nov. 8, Secretary of State Antony Blinken said.

"The military must reverse these actions immediately," he also said in a statement.

White House Press Secretary Jen Psaki said in a separate statement that the United States "opposes any attempt to alter the outcome of recent elections or impede Myanmar's democratic transition, and will take action against those responsible if these steps are not reversed."

The United States, in coordination with its regional partners, urges "the military and all other parties to adhere to democratic norms and the rule of law, and to release those detained," she also said, adding that Washington is "monitoring the situation closely."
