Canadians are being advised to avoid travelling to South Sudan, and to leave the country if they are there right now.
The Department of Foreign Affairs issued a travel advisory Saturday evening saying the situation "is increasingly unstable outside of (the capital of) Juba."
Non-essential staff and dependents have been authorized to leave for security reasons, the government said.
"You are urged to leave now by commercial means, as it may become increasingly difficult to do so if the situation deteriorates further. The Juba airport is open, and tickets for commercial flights are available," the advisory said.
