A significant security presence has been deployed throughout the country with officers and soldiers observed on patrol in key urban areas ahead of expected anti-government protests scheduled for the nation's independence anniversary.
By midday, however, no demonstrations had begun.
People living in Dar es Salaam, Arusha, Mbeya, Mwanza reported an unusually slow start to the day, with a large number opting to stay home due to doubts about whether protests would happen.
The protests were organized to call for political reforms in the wake of October's post-election unrest which resulted in an unconfirmed death toll.
The authorities have admitted employing force against demonstrators, claiming that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday streets that were largely deserted in the commercial capital, Dar es Salaam. This was a stark contrast to the city's usual weekday bustle.
The quiet was undercut by a persistent sense of tension.
Security vehicles were seen driving along primary thoroughfares and junctions, while personnel were stationed at key points, particularly near key public infrastructure.
Through online platforms, organizers advised followers to remain vigilant, implying that any protest activity would likely commence later in the day. The messaging echoed past mobilization efforts in the country, when turnout increased later in the day.
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 increased security or on the planned protests.
Tanzanian authorities have banned the intended demonstrations and cancelled independence day celebrations, urging citizens to stay indoors.
"The prevailing mood is one of quiet tension as people choose to stay home."
The overall situation painted a picture of a country under strain, where the potential for demonstration led to a security clampdown in advance that left conspicuously quiet typically busy cities.
