German Foreign Minister Guido Westerwelle has urged all parties in Egypt to find a prompt solution to the country's political crisis, Al-Ahram Arabic news website reported.

Westerwelle issued a statement on Thursday stressing that Egypt’s future cannot be decided by “confrontations.”

Egypt’s democratic transition requires the Muslim Brotherhood’s inclusion in the political scene, he added. “Paving the way for a stable future will not be achieved unless the democratic transition includes all civilian leaders.”

Westerwelle’s statement comes after Egyptian army chief Abdel-Fattah El-Sisi called for mass protests on Friday to give the military a mandate to combat "violence and terrorism."

Presidential spokesperson Ahmed El-Muslimani stated on Wednesday that the presidency backed El-Sisi's call for protests. 

"Egypt has already started a war on terrorism. El-Sisi's call for protests is to protect the revolution and the state," El-Muslimani added.
