Myanmar's generals ordered internet providers to restrict access to Facebook Thursday, as UN chief Antonio Guterres said the world must rally to ensure the military coup fails.
The Southeast Asian nation was plunged back into direct military rule on Monday as de facto leader Aung San Suu Kyi and other civilian leaders were detained in a series of dawn raids, ending the country's brief experiment with democracy.
The coup sparked international condemnation and fears the military will drag 54 million people back to the decades of junta rule that turned Myanmar into one of Asia's most impoverished and repressive nations.
With soldiers back on the streets of major cities, the takeover has so far not generated any mass pro-democracy street protests.
However, hundreds of supporters of the Tatmadaw, as the military is called, rallied in the capital Naypyidaw Thursday in support of the coup.
Some carried signs which read: "National betrayers who depend on foreign countries are not wanted" and "Tatmadaw loves the people... may you be successful."
People have flocked to social media to voice opposition and share plans for civil disobedience -- especially on Facebook.
"We have digital power... so we've been using this since day one to oppose the military junta," said activist Thinzar Shunlei Yi, who is behind a so-called "Civil Disobedience Movement" fanning out across social media platforms.
Telenor, one of the country's main telecoms providers, confirmed on Thursday authorities had ordered it to "temporarily block" Facebook access.
The Norwegian-owned company said it had to comply but "does not believe that the request is based on necessity and proportionality, in accordance with international human rights law".
Facebook confirmed access "is currently disrupted for some people" and urged authorities to restore connectivity.
NetBlocks, which monitors internet outages around the world, said the disruptions were also affecting Facebook-owned apps such as Instagram and WhatsApp.
For many in Myanmar, Facebook is the gateway to the internet and a vital way to gather information.
"The first thing we look at each morning is our phone, the last thing we look at in the night is our phone," said Aye, a 32-year-old entrepreneur opposed to the coup, who asked AFP to withhold her real name out of fear of reprisals.
A small rally kicked off Thursday in front of a medical university in the northern city of Mandalay, with protesters carrying signs that read: "People's protest against the military coup!"
Local media said police arrested four people, although authorities could not confirm the detentions to AFP.
Meanwhile, 70 MPs from Suu Kyi's National League for Democracy party signed a "pledge to serve the public" while staging their own symbolic parliamentary session in Naypyidaw, according to local media.
On Wednesday, UN Secretary-General Guterres said he would pressure the generals to reverse course, in his most forceful comments yet.
"We will do everything we can to mobilise all the key actors and international community to put enough pressure on Myanmar to make sure that this coup fails," Guterres told The Washington Post.
Suu Kyi, who has not been seen in public since she was detained, won a huge landslide with her NLD, while the military's favoured parties received a drubbing.
International and local observers -- as well as Myanmar's own election monitor -- reported no major issues that might have affected the integrity of the vote.
Myanmar's junta-era constitution ensures the military retains considerable influence, including a quarter of parliamentary seats and control of key ministries.
But analysts say top generals feared their influence was waning and were dismayed by the enduring appeal of Suu Kyi.
On Wednesday, authorities brought an obscure charge against the 75-year-old to justify her ongoing detention.
According to her party, she was charged with an offence under Myanmar's import and export law after authorities found unregistered walkie-talkies at her home.
Myanmar's military has declared a one-year state of emergency and said it will hold new elections once its allegations are addressed.
That has caused huge anger inside the nation and the "Civil Disobedience Movement" appears to have taken off.
By Thursday, red NLD flags adorned the balconies of dozens of Yangon apartments -- a tacit but vibrant show of resistance against the military.
Residents have also started clanging pots and cymbals nightly at 8 pm to "drive the military junta out" -- a throwback to an old Myanmar tradition of expelling evil spirits.
Health workers this week also pinned red ribbons on their scrubs to signify their support for the NLD, with some boycotting work.
During junta rule dissent was quashed, with thousands of activists -- including Suu Kyi -- detained for years on end.
Censorship was pervasive and the military frequently deployed lethal force, most notably during huge protests in 1988 and 2007.
The new government has already issued a warning telling people not to say or post anything that might "encourage riots or an unstable situation".
Diplomats said veto-wielding China and Russia, Myanmar's main supporters at the UN, had asked for more time to finesse the council's response.
