Even though the U.S. and many others have described the army's acts as a coup, the Security Council's unanimous announcement didn't.
The army has said it acted legally and constitutionally since the authorities had refused to tackle its complaints which last November's overall election, where Suu Kyi's party won a landslide victory, was marred by widespread voting irregularities.
About 70 recently chosen lawmakers defied the new military authorities on Thursday by convening a symbolic assembly of this Parliament which was prevented from launching. They signed up their oaths of office in a government guesthouse in the capital, Naypyitaw, at which roughly 400 of these were arrested in the wake of the takeover. They've since been told that they are able to go back to their home districts.
The unofficial convening has been a symbolic gesture to claim that they, not the army, would be the nation's legitimate lawmakers.
Many expressed their anger and their decision to resist the coup since they left the guesthouse.
"This violates the individual rights of the entire citizenry. This isn't a coup. This really is a treason against the authorities.
The army set all state powers to the hands of the junta, such as legislative acts, during a yearlong country crisis. Additionally, it intends to form a fresh election commission to research its own allegations of voting irregularitiesto hold a new election in the close of the state of crisis and also to turn over power to the winner.

The protests have revived a tune related to a collapsed 1988 uprising against military dictatorship.
Videos posted on societal media revealed medical employees and many others singing"Kabar Makyay Bu" -- "We Will Not Be Satisfied Until the End of the World" -- sung to the tune of"Dust in the Universe," a 1977 tune by the U.S. rock band Kansas.
Countless men and women of the funding Naypyitaw combined a rally in support of their military coup on Thursday, the most recent of a range of occasions which aim to project a picture of hot endorsement of their power grab.

Her celebration said the complaint against her is owning illegally stolen walkie-talkies, which have been discovered in her home and were thought to be employed by her bodyguards.

"Telecom providers in Myanmar have already been ordered to block Facebook. We recommend authorities to reestablish connectivity to ensure individuals in Myanmar can communicate with family members and friends and get important information," Facebook stated in a statement.
In 2018, Facebook eliminated several reports connected to Myanmar's army, such as that of Old Gen. Min Aung Hlaing, the new administration's chief, since their content seemed to fuel hatred toward the Muslim Rohingya minority. The Rohingya were targeted at a barbarous 2017 military counterinsurgency effort that drove over 700,000 to neighboring Bangladesh. The International Court of Justice continues to be hearing a case claiming the military's activities constituted genocide.
A Norway-based humanitarian group said Myanmar's political catastrophe could make a humanitarian catastrophe affecting 1 million vulnerable individuals if international aid groups are limited further.
Jan Egeland, head of the Norwegian Refugee Councilsaid that it was"deeply troubled" that Monday's takeover from the army could influence"people's capacity to get humanitarian help."
