BBC NEWS/A near-total internet blackout is in effect with connectivity falling to 16% of ordinary levels, said the monitoring group NetBlocks Internet Observatory.
In the main city, Yangon, crowds chanted “Military dictator, fail, fail; Democracy, win, win”.
Police with riot shields have blocked the main roads into the city centre.
The internet shutdown happened hours after the military blocked access to Twitter and Instagram to stop people mobilising for protests. Facebook had been banned a day earlier.
