A significant security presence has been deployed across Tanzania with police and military seen patrolling key urban areas in anticipation of anticipated anti-government protests called to coincide with the nation's independence anniversary.
By midday, however, no demonstrations had begun.
Residents in Dar es Salaam, Arusha, Mbeya, Mwanza 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 demonstrations were called to demand political reforms in the wake of the unrest that followed last October's elections which resulted in an unconfirmed death toll.
Officials have conceded employing force against demonstrators, asserting 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 was a stark contrast to the city's usual weekday bustle.
The quiet was undercut by a persistent sense of tension.
Security vehicles were seen driving along major roads and intersections, while personnel were stationed at strategic locations, including around key public infrastructure.
On social media, activists and campaigners urged 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 frequent checks at roadblocks, where officers questioned drivers about where they were headed.
The government has not issued detailed comments on the heightened security measures or on the scheduled demonstrations.
Tanzanian authorities have banned the planned protests and called off independence anniversary events, urging citizens to stay indoors.
"An eerie quiet masks the underlying tension felt by those indoors."
The overall situation depicted a country under strain, where the potential for demonstration resulted in a preemptive security lockdown that left conspicuously quiet typically busy cities.
