A significant security presence has been deployed across Tanzania with police and military seen patrolling major cities ahead of expected demonstrations against the government called to coincide with the nation's independence anniversary.
By midday, however, no demonstrations had begun.
Residents in several major urban centers reported an unusually slow start to the day, with a large number opting to stay home due to doubts about whether protests would happen.
The protests were organized to call for changes to the political system following the unrest that followed last October's elections which left an unknown number of people dead.
Officials have conceded employing force against demonstrators, asserting that some groups were attempting to overthrow the regime.
Correspondents noted on Tuesday nearly empty streets in the commercial capital, Dar es Salaam. This stood in sharp contrast to the city's typical weekday activity.
Although quiet, the atmosphere remained tense.
Armored vehicles were spotted cruising along primary thoroughfares and junctions, while personnel were stationed 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.
Authorities have not provided specific statements on the increased security or on the scheduled demonstrations.
Tanzanian authorities have banned the planned protests 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 painted a picture of a nation on edge, where the potential for demonstration resulted in a security clampdown in advance that left conspicuously quiet typically busy cities.
