Hundreds of people have rallied in Myanmar’s main city, Yangon, to protest against this week’s military coup.
“Military dictator, fail, fail; Democracy, win, win,” chanted the crowd, the largest protest seen since the military took over.
They called for release of the elected leader Aung San Suu Kyi and others detained by the army.
The protest came despite the military’s efforts to stop people mobilising by shutting down social media.
On Friday evening, Telenor, one of the country’s main internet providers, confirmed it had been ordered to deny access to the two sites “until further notice”.
The coup leaders blocked Facebook on Thursday for the sake of “stability”.
And on Saturday, unconfirmed reports emerged of a total internet shutdown.
Aung San Suu Kyi is under house arrest, according to her lawyer. Police documents show she is accused of illegally importing and using communications equipment – walkie-talkies – at her home in Nay Pyi Taw.
Why has social media been blocked?
Many Burmese had watched the 1 February coup unfold in real time on Facebook, which is the country’s primary source of information and news. But three days later, internet providers were ordered to block the platform for stability reasons.
Following the ban, thousands of users were active on Twitter and Instagram using hashtags to express their opposition to the takeover. By 22:00 local time (15:30 GMT) on Friday access to those platforms had also been denied.
