Sudan's PM Abdalla Hamdok intends to resign within hours, sources say
While several political forces took part in drafting the agreement, according to the sources, it has faced widespread criticism from parties and the general public.
On Saturday, hundreds of thousands of people marched on the presidential palace rejecting both military rule and Hamdok's decision to return, which he said he took to preserve gains made during the transition and to end the bloodshed.
Some 47 people have died in crackdowns on protests against military rule, including two as a result of Saturday's protest.
The United Nations said on Tuesday that it had received reports of rape or gang rape of 13 women and girls.
Sources close to Hamdok said previously he would only remain in office if he had the political support and if the agreement was enforced.
In a statement over the weekend, Hamdok said Sudan was inching towards "the abyss," blaming political intransigence and lack of consensus on a new political agreement.
The group Hamdok spoke to on Tuesday called on him to stay in his position but he insisted he would leave, the sources added.
