A significant security presence has been deployed throughout the country with officers and soldiers observed on patrol in major cities ahead of anticipated demonstrations against the government scheduled for the nation's independence anniversary.
Midday arrived without any sign of the planned demonstrations.
Residents 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 demonstrations were called to call for changes to the political system following October's post-election unrest which left an unknown number of people dead.
Officials have conceded using force against protesters, asserting that certain elements aimed to topple the government.
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 usual weekday bustle.
While quiet, a palpable tension filled the air.
Security vehicles were seen driving along major roads and intersections, while officers took up positions 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 previous protest calls in Tanzania, when turnout increased later in the day.
Motorists who ventured out reported regular stops at security checkpoints, where police interrogated motorists about their destinations.
The government has not issued detailed comments on the increased security or on the planned protests.
The government has prohibited 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 day's events depicted a country under strain, where the potential for demonstration led to a security clampdown in advance that left conspicuously quiet normally bustling urban centers.
