The former foreign minister of Sudan, Mariam al-Sadiq al-Mahdi, says she doubts the rival military factions can agree on a genuine ceasefire due to their deep mistrust.
Representatives of the army and the paramilitary Rapid Support Forces (RSF) are currently meeting in Saudi Arabia.
In an interview with BBC Focus on Africa radio, the ex-minister said that officials loyal to former President Omar al-Bashir were trying to ensure the army’s fight against the RSF continued.
She added that people calling for peace, including herself, were increasingly being labelled as traitors.
She described the war as senseless, and said that fighters did not want to help civilians get out of the capital, Khartoum, as they were using them as human shields.
Millions of residents are facing increasing hardships and dwindling supplies of essential goods.
Phone and internet companies have also been shutting down their services due to lack of fuel.
