One week after a military takeover, protest crowds grew bigger and bolder in Myanmar this weekend, while remaining nonviolent. Tens of thousands of demonstrators demanded the military release from detention Aung San Suu Kyi, the country’s ousted leader, and other top figures from her National League for Democracy party.The coup and the protests are a reminder of the long and bloody struggle for democracy in a country that the military ruled directly for more than five decades. Uprisings in 1988 and 2007 were quashed by deadly military force. In 2015, Ms. Suu Kyi’s party won a landslide election but faced a number of curbs to its power under a military-drafted constitution. The military showed restraint this weekend, meeting protests with riot police but not soldiers. As protests grew Saturday, the authorities cut most access to the internet. Access was mostly restored Sunday afternoon, but social media platforms, often used to to organize and to share news, were still partially shut down.
