A visit to the US by a top South Sudanese rebel commander, Gen Thomas Cirilo, is causing jitters in his home country.
A report by The Dawn daily in Juba on Tuesday, suggested that the trip to Washington was part of a wider American plot against the latest South Sudan peace agreement.
The deal was negotiated in Khartoum.
"We are not sure of why he is gone to the US, but we know he is there, being sponsored by the CIA," The Dawn daily quoted intelligence sources as saying.
The paper said the rebel commander was rallying support from the South Sudanese diaspora to fulfill his motive of overthrowing the Juba regime.
Gen Cirilo is the leader of a faction of the National Salvation Front/ Army.
His faction confirmed his presence in Washington, but did not give details.
The rebel commander publicly rejected to sign the final power sharing and security arrangements pact on August 5, 2018 in Khartoum.
He also declined to initial the final peace accord last week, citing lack of credibility in the deal.
Gen Cirilo further blasted the peace guarantors, Sudan and Uganda, claiming they were after their interests than achieving lasting stability in South Sudan.
The rebel leader demanded that a federal system of governance be introduced in South Sudan.
The former Army deputy Chief declared rebellion against President Salva Kiir in 2016 and accused the latter of implementing a tribal agenda.
