A significant security presence has been deployed throughout the country with officers and soldiers observed on patrol in major cities ahead of expected demonstrations against the government called to coincide with independence day.
As of noon, however, no protests had materialized.
People living in several major urban centers reported an unusually slow start to the day, with many people choosing to remain indoors amid uncertainty over whether protests would happen.
The protests were organized to demand political reforms following October's post-election unrest which left an unknown number of people dead.
The authorities have admitted using force against protesters, claiming that some groups were attempting to overthrow the regime.
On Tuesday, reporters observed nearly empty streets in the commercial capital, 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 officers took up positions at strategic locations, including around key public infrastructure.
On social media, activists and campaigners urged followers to remain vigilant, suggesting any demonstrations were unlikely to begin until the afternoon. This communication mirrored past mobilization efforts in the country, when turnout increased later in the day.
Drivers who went out experienced regular stops at security checkpoints, where officers questioned drivers about where they were headed.
Authorities have not provided detailed comments on the increased security or on the scheduled demonstrations.
Tanzanian authorities have banned the intended demonstrations and called off independence anniversary events, advising the public to remain at home.
"An eerie quiet masks the underlying tension felt by those indoors."
The overall situation depicted a nation on edge, where the potential for demonstration led to a security clampdown in advance that left conspicuously quiet typically busy urban centers.
