Security has been tightened across Tanzania with police and military seen patrolling major cities ahead of expected demonstrations against the government scheduled for the nation's independence anniversary.
As of noon, however, no protests had materialized.
Residents in several major urban centers noted the day began with unusual quietness, with a large number opting to stay home due to doubts about whether protests would happen.
The protests were organized to demand changes to the political system following October's post-election unrest which left an unknown number of people dead.
The authorities have admitted employing force against demonstrators, asserting that certain elements aimed to topple the government.
Correspondents noted on Tuesday nearly empty streets in the business hub, Dar es Salaam. This was a stark contrast to the city's typical weekday activity.
Although quiet, the atmosphere remained tense.
Armored vehicles were spotted cruising along major roads and intersections, while officers took up positions at strategic locations, particularly near important public buildings and facilities.
On social media, activists and campaigners urged followers to remain vigilant, implying that any protest activity would likely commence later in the day. This communication mirrored previous protest calls in Tanzania, when participation grew as the day progressed.
Drivers who went out experienced regular stops at security checkpoints, where officers questioned drivers about their destinations.
The government has not issued specific statements on the heightened security measures or on the planned protests.
Tanzanian authorities have banned the intended demonstrations and called off independence anniversary events, advising the public to remain at home.
"An eerie quiet masks the underlying tension felt by those indoors."
The overall situation depicted a nation on edge, where the threat of protest resulted in a preemptive security lockdown that effectively emptied normally bustling cities.
