A nationwide strike marked the one-year anniversary Tuesday of the army’s seizure of power in Myanmar, as protests and sporadic violence across the country renewed concern over the ongoing struggle for power.

Photos and videos on social media showed a “silent strike” emptied streets in the largest city of Yangon and other towns as people stayed home and businesses shut in a show of opposition to army rule.

Violence was reported as well, as the country faces an insurgency that some UN experts now characterize as a civil war.
