Myanmar's biggest city Yangon woke to a heavy army presence on Monday.
Military and police vehicles had criss-crossed the city overnight. Armoured personnel carriers were seen in several areas of the city, along with army trucks.
A near-total internet shutdown was reported on Sunday night, as mass protests against the military coup of February 1 entered their second week.
Pick-up trucks blaring sirens slowly moved through streets, full with security personnel.
The heavy military and police presence prompted anxiety that a wave of arrests was imminent.
It isn't yet clear the extent of overnight action by the authorities against individuals associated with the protest movement.
