Armored vehicles have rolled into Myanmar’s major cities, night raids are being conducted on prominent coup critics, and internet access has been largely cut off amid fears of a crackdown on anti-coup protesters. This comes after nine straight days of mass city protests.

Al Jazeera reported that then the military rolled out armored vehicles into Yangon, Myanmar’s largest city, as well as into the cities of Myitkyina and Sittwe. This is the first widespread use of the military’s armored vehicles since the early February coup overthrew the government. 

On Monday morning in Yangon’s Sule Pagoda, which has been the epicenter of demonstrations against the coup, the police deployed a dozen trucks with four of them containing water cannons. 

In one incident, posted to Facebook Live, security forces in Myitkyina, the capital of the country’s northern Kachin state, fired on protesters at a power plant on Sunday, after a crowd had gathered there fearing that the military was about to cut off the electricity. It is unclear whether live rounds or rubber bullets were used. 

Video shows security forces using water cannons. Then protesters, who had built barricades of tires, began to throw stones. Military members then fired several rounds at the crowd. Five journalists reporting on the incident were allegedly arrested.

The United States Embassy warned Americans in Myanmar to shelter in place and not to venture out due to the possibility of violence. It also warned U.S. citizens about a possible country-wide internet outage from 1:00 a.m. to 9:00 a.m.
