Security has been tightened across Tanzania with police and military seen patrolling key urban areas in anticipation of expected anti-government protests called to coincide with independence day.
By midday, however, no demonstrations had begun.
Residents in several major urban centers noted the day began with unusual quietness, with a large number opting to stay home amid uncertainty over if the demonstrations would proceed.
The demonstrations were called to call for political reforms following the unrest that followed last October's elections which resulted in an unconfirmed death toll.
The authorities have admitted using force against protesters, asserting that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday nearly empty streets in the business hub, Dar es Salaam. This stood in sharp 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 strategic locations, particularly near important public buildings and facilities.
Through online platforms, organizers advised supporters to stay alert, implying that any protest activity would likely commence later in the day. The messaging echoed 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 specific statements on the heightened security measures 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.
"The prevailing mood is one of quiet tension as people choose to stay home."
The overall situation painted a picture of a nation on edge, where the threat of protest resulted in a security clampdown in advance that effectively emptied normally bustling cities.
