A significant security presence has been deployed across Tanzania with officers and soldiers observed on patrol in key urban areas ahead of anticipated demonstrations against the government called to coincide with independence day.
By midday, however, no demonstrations had begun.
Residents in Dar es Salaam, Arusha, Mbeya, Mwanza reported an unusually slow start to the day, with many people choosing to remain indoors due to doubts about whether protests would happen.
The demonstrations were called to demand political reforms following the unrest that followed last October's elections which left an unknown number of people dead.
The authorities have admitted employing force against demonstrators, claiming that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday streets that were largely deserted in the business hub, Dar es Salaam. This stood in sharp contrast to the city's typical weekday activity.
Although quiet, the atmosphere remained tense.
Security vehicles were seen driving along primary thoroughfares and junctions, while personnel were stationed at key points, including around key public infrastructure.
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 participation grew as the day progressed.
Motorists who ventured out reported regular stops at security checkpoints, where officers questioned drivers about their destinations.
Authorities have not provided specific statements on the heightened security measures or on the scheduled demonstrations.
Tanzanian authorities have banned the intended demonstrations and cancelled independence day celebrations, advising the public to remain at home.
"The prevailing mood is one of quiet tension as people choose to stay home."
The day's events depicted a country under strain, where the threat of protest resulted in a security clampdown in advance that left conspicuously quiet typically busy cities.
