Security has been tightened across Tanzania with officers and soldiers observed on patrol in key urban areas in anticipation of expected demonstrations against the government called to coincide with independence day.
Midday arrived without any sign of the planned demonstrations.
Residents in several major urban centers noted the day began with unusual quietness, with a large number opting to stay home amid uncertainty over whether protests would happen.
The demonstrations were called to call for changes to the political system following the unrest that followed last October's elections which left an unknown number of people dead.
The authorities have admitted employing force against demonstrators, claiming that certain elements aimed to topple the government.
Correspondents noted on Tuesday streets that were largely deserted in the business hub, Dar es Salaam. This stood in sharp contrast to the city's typical weekday activity.
The quiet was undercut by a persistent sense of tension.
Armored vehicles were spotted cruising along primary thoroughfares and junctions, while personnel were stationed at strategic locations, particularly near important public buildings and facilities.
On social media, activists and campaigners urged followers to remain vigilant, suggesting any demonstrations were unlikely to begin until the afternoon. The messaging echoed previous protest calls in Tanzania, when participation grew as the day progressed.
Motorists who ventured out reported regular stops at security checkpoints, where officers questioned drivers about their destinations.
The government has not issued detailed comments on the heightened security measures or on the planned protests.
The government has prohibited the intended demonstrations and called off independence anniversary events, urging citizens to stay indoors.
"The prevailing mood is one of quiet tension as people choose to stay home."
The day's events painted a picture of a nation on edge, where the potential for demonstration led to a preemptive security lockdown that left conspicuously quiet normally bustling urban centers.
