Tens of thousands of people joined in peaceful protests in the city of Yangon, Myanmar, on Saturday and Sunday.

According to various news outlets, the crowds are growing in Yangon and Mandalay, the country’s second-largest city. Protesters are demanding the release of de facto leader Aung San Suu Kyi, who was arrested during the coup. 

The military also arrested many government leaders. It charged Kyi with illegally importing and using communications equipment — walkie-talkies — for her security detail. 

Protesters marched carrying signs with Suu Kyi’s picture reading “We want our leader, Free Daw Aung Suu Kyi.” She and other lawmakers were detained by the military in pre-dawn raids on Monday.
