Security has been tightened throughout the country with officers and soldiers observed on patrol in major cities in anticipation of anticipated anti-government protests scheduled for independence day.
Midday arrived without any sign of the planned demonstrations.
People living in several major urban centers reported an unusually slow start to the day, with many people choosing to remain indoors due to doubts about whether protests would happen.
The protests were organized to call for political reforms in the wake of the unrest that followed last October's elections which resulted in an unconfirmed death toll.
Officials have conceded using force against protesters, 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 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, particularly near important public buildings and facilities.
Through online platforms, organizers advised 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 officers questioned drivers about where they were headed.
The government has not issued detailed comments on the increased security or on the planned protests.
The government has prohibited the intended demonstrations and cancelled independence day celebrations, urging citizens to stay indoors.
"With many staying at home the atmosphere is quiet but tense."
The overall situation depicted a country under strain, where the threat of protest led to a security clampdown in advance that effectively emptied typically busy urban centers.
