Most primary schools visited this morning either had no classes or had dismissed students before 10am.
Students from Ted Diro Primary School said they were sent home early but will have normal classes on Wednesday.
Police personnel were also seen on foot patrol around the city, conducting random checks.
The road to the Parliament from the National Court as well as from the International Convention Centre was blocked off.
About 1,000 policemen and women have been deployed around the city beginning Monday.
This includes a 300-man team from the Bomana Police College, plus personnel from Police Headquarters, three mobile squads from McGregor barracks, the Police Dog Unit and NCD operational units.
Deputy Commissioner Jim Andrews said the security operation code-named ‘Lukautim-City’ will be headed by NCD/Central Commander Donald Yamasombi and it will remain enforced for several days in the lead up to, during and after the anticipated Vote of No Confidence.
