A significant security presence has been deployed throughout the country with police and military seen patrolling major cities in anticipation of anticipated demonstrations against the government scheduled for the nation's independence anniversary.
As of noon, however, no protests had materialized.
People living in several major urban centers reported an unusually slow start to the day, with a large number opting to stay home due to doubts about if the demonstrations would proceed.
The demonstrations were called to call for changes to the political system following October's post-election unrest which resulted in an unconfirmed death toll.
Officials have conceded employing force against demonstrators, claiming that some groups were attempting to overthrow the regime.
On Tuesday, reporters observed streets that were largely deserted in the business hub, Dar es Salaam. This was a stark contrast to the city's typical weekday activity.
While quiet, a palpable tension filled the air.
Security vehicles were seen driving along primary thoroughfares and junctions, while personnel were stationed at key points, including around important public buildings and facilities.
On social media, activists and campaigners urged supporters to stay alert, suggesting any demonstrations were unlikely to begin until the afternoon. This communication mirrored past mobilization efforts in the country, when participation grew as the day progressed.
Drivers who went out experienced regular stops at security checkpoints, where police interrogated motorists about where they were headed.
Authorities have not provided detailed comments on the heightened security measures or on the planned protests.
Tanzanian authorities have banned the intended demonstrations and cancelled independence day celebrations, advising the public to remain at home.
"An eerie quiet masks the underlying tension felt by those indoors."
The overall situation painted a picture of a country under strain, where the potential for demonstration led to a preemptive security lockdown that left conspicuously quiet normally bustling cities.
