A political crisis in Myanmar “constitutes a military coup d’etat,” according to a new analysis from Secretary of State Antony Blinken’s team.

“After a careful review of the facts and circumstances, we have assessed that Aung San Suu Kyi, the leader of Burma’s ruling party, and Win Myint, the duly elected head of government, were deposed in a military coup on Feb. 1,” a senior State Department official told reporters Tuesday. “We continue to call on the Burmese military leadership to release them — and all other detained civil society and political leaders — immediately and unconditionally.”
