The commission investigating violations in said on Wednesday it was dismayed by the ongoing harassment and intimidation of rights defenders, journalists and civil society figures.

The world's newest nation has suffered from chronic instability since independence in 2011, with a coalition of civil society groups urging the government to step down, saying they have "had enough".

The commission said credible threats to certain people's lives by the National Security Services (NSS) had caused someÌýto flee the country, while the NSS continues to harass their colleagues and families.

"Civic space in South Sudan is eroding at an accelerating pace, undermining efforts to achieve a sustainable peace," the commission's chair Yasmin Sooka said in a statement.

"The role played by overzealous security services in preventing dissent and criticism, causing key stakeholders involved in constitutional and transitional justice processes to flee the country, discourages the participation of others."

Commissioner Andrew Clapham said the state's targeting of high-profile human rights defenders would have a "chilling effect" on civil society and corrode confidence in processes such as national elections.

He said that while progress on a 2018 peace deal which ended a brutal civil war had been slow, in recent months government leaders had taken some forward steps.

However, such moves come while the NSS has been targeting prominent civil society figures.

"The NSS threaten peace and must be reigned in," said Clapham.

Numerous civil society leaders remain detained and the commission is concerned their detention is arbitrary.
