A significant security presence has been deployed throughout the country with police and military seen patrolling major cities in anticipation of expected anti-government protests scheduled for the nation's independence anniversary.
As of noon, however, no protests had materialized.
Residents in several major urban centers reported an unusually slow start to the day, with a large number opting to stay home amid uncertainty over if the demonstrations would proceed.
The demonstrations were called to demand changes to the political system following the unrest that followed last October's elections which resulted in an unconfirmed death toll.
The authorities have admitted using force against protesters, asserting that certain elements aimed to topple the government.
Correspondents noted on Tuesday nearly empty streets in the business hub, Dar es Salaam. This stood in sharp contrast to the city's typical weekday activity.
Although quiet, the atmosphere remained tense.
Security vehicles were seen driving along major roads and intersections, while personnel were stationed at key points, particularly near key public infrastructure.
Through online platforms, organizers advised supporters to stay alert, implying that any protest activity would likely commence later in the day. The messaging echoed previous protest calls in Tanzania, when participation grew as the day progressed.
Drivers who went out experienced frequent checks at roadblocks, where officers questioned drivers about where they were headed.
Authorities have not provided specific statements on the heightened security measures or on the planned protests.
Tanzanian authorities have banned the planned protests and cancelled independence day celebrations, urging citizens to stay indoors.
"With many staying at home the atmosphere is quiet but tense."
The overall situation painted a picture of a nation on edge, where the threat of protest resulted in a security clampdown in advance that left conspicuously quiet typically busy urban centers.
