The United Nations says unknown gunmen seized eight foreign and local contractors outside a civilian protection site in South Sudan's capital before releasing them two days later.
The abduction highlights the insecurity in the East African nation as civil war moves well into its fourth year.
The UN mission in South Sudan said the employees of a private company contracted to a non-governmental organization were seized Friday in Juba while drilling for water and were released unharmed Sunday.
Four of the eight employees were foreigners; the UN did not give their nationalities.
The UN said the release followed negotiations led by South Sudan's security services.
Violence has been escalating in and around the UN civilian protection sites, where more than 200,000 people have sought shelter from the fighting.
