Businesses in Zimbabwe's capital, Harare close its doors as they wait for the results from the presidential election.
Armed soldiers and police are on patrol in the capital city.
Three people were killed in the city on Wednesday in clashes between the security forces and supporters of opposition leader Nelson Chamisa.
The opposition leader says Monday's elections were rigged to give President Emmerson Mnangagwa victory.
The elections were the first since long-time ruler Robert Mugabe was ousted in November.
Members of the Steel Workers Union of Trinidad & Tobago has signalled its intention to protest at the Couva roundabout from 6 am on Tuesday. The Union says this action results from allegations that the Nu-Iron Unlimited is about to purchase the entire Steel Plant facility formerly known as ArcelorMittal.
Its members say that the company is purchasing the ArcelorMittal Steel Plant for less than the value of the unpaid separation benefits of the former workers.
