The top US diplomat for Africa is going to Sudan this week amid the unrest there, the state department says.
Tibor Nagy, the US assistant secretary for Africa, will "call for a cessation of attacks against civilians".
The state department said Mr Nagy would "urge parties to work towards creating an enabling environment" for talks between the two sides to resume.
He will also discuss the situation with the Ethiopian Prime Minister, Abiy Ahmed, who has been trying to mediate between the military council and the opposition in Sudan, before later travelling to Mozambique and South Africa, BBC reports.
