The national government urged citizens to report ‘strange objects’ and leave them undisturbed.
The advice came one day after five people were killed by an old bomb in Suk Sita, Juba.
Government spokesperson Michael Makuei told reporters at the end of Friday’s ordinary Council of Ministers that the Cabinet offered their condolences to the bereaved families.
He urged people not to touch strange objects they may find but report them to the authorities to avoid live threatening risks.
Mr Makuei also said South Sudan celebrates on Monday Global Hand Washing Day in Juba involving pupils from six schools in Gudele.
The event is organized by the Water ministry.
