In an upwelling of anger in the country’s largest city protesters chanted, “Military dictator, fail, fail; Democracy, win, win” and held banners reading “Against military dictatorship”. Bystanders offered them food and water.
Many in the crowd wore red, the colour of Suu Kyi’s National League for Democracy (NLD) which won Nov. 8 elections in a landslide, a result the generals have refused to recognise claiming fraud.
Yangon streets had a festival atmosphere late Saturday as a cacophony of car horns blared and thousands marched toward City Hall. Drivers leaned out of their cars and raised the three-finger salute. Bystanders returned the gesture. Some held up NLD flags or pictures of Suu Kyi. Many clapped and danced.
The protest built despite a blockade of the internet imposed after they first began to gather.
Monitoring group NetBlocks Internet Observatory reported a “national-scale internet blackout”, saying on Twitter that connectivity had fallen to 16% of ordinary levels. Witnesses reported a shutdown of mobile data services and wifi.
The junta did not respond to requests for comment. It extended a social media crackdown to Twitter and Instagram after seeking to silence dissent by temporarily blocking Facebook, which counts half of the population as users.
Facebook said it was “extremely” concerned about the internet shutdown, “strongly” urging the junta to unblock social media.
“At this critical time, the people of Myanmar need access to important information and to be able to communicate with their loved ones,” Facebook’s head of public policy for Asia-Pacific emerging countries, Rafael Frankel, said in a statement.
The United Nations human rights office said on Twitter that “internet and communication services must be fully restored to ensure freedom of expression and access to information.”
Norwegian mobile network provider Telenor ASA said authorities had ordered all mobile operators to temporarily shut down the data network, although voice and SMS services remained open.
Many activists had sidestepped the Facebook ban by using virtual private networks to conceal their locations, but the more general internet disruption will severely limit their ability to organise and access independent news and information.
Myanmar civil society organisations appealed to internet providers and mobile networks to resist the junta’s orders, saying in a joint statement they were “essentially legitimising the military’s authority”.
Telenor said it had stressed to the authorities that access to telecom services should be maintained. However it added it was bound by local law and its first priority was the safety of its local workers.
“We deeply regret the impact the shutdown has on the people in Myanmar,” it said in a statement.
Amnesty International’s deputy regional director for campaigns, Ming Yu Hah, said shutting down the internet amid a coup and the COVID-19 pandemic was a “heinous and reckless decision”.
Army chief Min Aung Hlaing seized power alleging fraud, although the electoral commission says it has found no evidence of widespread irregularities in the November vote.
The junta announced a one-year state of emergency and has promised to hand over power after new elections, without giving a timeframe.
Nobel Peace laureate Suu Kyi, 75, has been charged with illegally importing six walkie-talkies, while ousted President Win Myint is accused of flouting COVID-19 restrictions. Neither has been seen since the coup. Their lawyer said they were being held in their homes.
NLD member Aung Moe Nyo, chief minister of the Magway region, said on Facebook before the shutdown: “It is not OK to let the country fall under junta government. I am very much thankful to those who oppose this, to those government staff who oppose this. This act is to save the country.”
Sean Turnell, an Australian economic adviser to Suu Kyi, said in a message to Reuters on Saturday he was being detained.
Australia’s government, without naming Turnell, said it had summoned the Myanmar ambassador to register “deep concern” over the arbitrary detention of Australian and other foreign nationals in Myanmar.
A civil disobedience movement has been building in Myanmar all week, with doctors and teachers among those refusing to work. Every night people bang pots and pans in a show of anger.
The coup has sparked international outrage, with the United States considering sanctions against the generals and the U.N. Security Council calling for the release of all detainees.
It has also deepened tensions between the United States and China, which has close links to Myanmar’s military. Secretary of State Antony Blinken pressed top Chinese diplomat Yang Jiechi in a phone call on Friday to condemn the coup, the State Department said.
The generals have few overseas interests that would be vulnerable to international sanctions, but the military’s extensive business investments could suffer if foreign partners leave - as Japanese drinks company Kirin Holdings said it would on Friday.
Suu Kyi spent 15 years under house arrest after leading pro-democracy protests against the long-ruling military junta in 1988.
After sharing power with a civilian government, the army began democratic reforms in 2011. That led to the election of the NLD in a landslide victory four years later. November’s election was meant to solidify a troubled democratic transition.
