The drastic changes in Egypt's political scene have not only fueled widespread concerns for the fate of Mohamed Morsi, the country's first president elected through a national poll, they have also ignited deep worries that the most populous Arab country may plunge deeper into political crisis and social unrest.

On Wednesday, the Egyptian military ousted Morsi, suspen- ded the constitution and called for new elections. Adli Mansour, head of the Supreme Constitutional Court, was sworn in as interim leader on Thursday.

Defense Minister and head of Egypt's armed forces General Abdel Fattah al-Sisi said Morsi had "failed to meet the demands of the people".
