A significant security presence has been deployed across Tanzania with officers and soldiers observed on patrol in key urban areas in anticipation of expected demonstrations against the government scheduled for independence day.
By midday, however, no demonstrations had begun.
People living in several major urban centers reported an unusually slow start to the day, with a large number opting to stay home amid uncertainty over whether protests would happen.
The protests were organized to demand changes to the political system in the wake of the unrest that followed last October's elections which left an unknown number of people dead.
Officials have conceded using force against protesters, asserting 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 typical weekday activity.
While quiet, a palpable tension filled the air.
Security vehicles were seen driving along primary thoroughfares and junctions, while officers took up positions at strategic locations, particularly near key public infrastructure.
On social media, activists and campaigners urged 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 their destinations.
The government has not issued specific statements on the increased security or on the scheduled demonstrations.
Tanzanian authorities have banned the intended demonstrations and cancelled independence day celebrations, advising the public to remain at home.
"With many staying at home the atmosphere is quiet but tense."
The overall situation depicted a nation on edge, where the threat of protest led to a preemptive security lockdown that left conspicuously quiet typically busy urban centers.
