Egyptian President Abdel Fattah al-Sisi will lead two emergency summits with other African leaders on Tuesday to address developments in Sudan and Libya, his presidency said.
The leaders will focus on "the evolution of the situation in Sudan.”
They will also seek to "stem the current crisis" in Libya, Egypt's presidency said in a statement.
Sisi is the current president of the African Union.
He will receive Chadian President Idriss Deby, Rwanda's head of state Paul Kagame, Congo's Denis Sassou-Nguesso, Somalia's Mohamed Abdullahi Mohamed and South Africa's Cyril Ramaphosa as well as Dijbouti's leader Ismail Omar Guelleh.
The planned summits are the first to be convened by African leaders on the current crises in Sudan and Libya.
For Sudan, the objective "is to discuss ... the most appropriate ways to address the evolution of the situation and to contribute to stability and peace", Egypt's presidency said.
President of the African Union commission Moussa Faki is also expected to participate in the discussions, along with officials from Ethiopia, South Sudan, Uganda, Kenya and Nigeria.
Another summit on Libya, which will bring together the leaders of Rwanda, South Africa and the Congo with Sisi, will focus on "relaunching a political process... (and) the elimination of terrorism", Egypt's presidency said.
