CAIRO - Egyptian judge Adli Mansour was sworn in Thursday as the interim president of the state after the ouster of Mohamed Morsi. Adli has taken an oath earlier in the day as head of the Supreme Constitutional Court (SCC).

"I swear by almighty God that I will sincerely protect the republican order and that I fully respect the constitution and the rule of law and completely take care of people's interests, preserve the nation's independency and safety of its lands," Adli said during the ceremony.

He also promised to lead "a modern, constitutional, national and civil country."

At least 11 people were killed and more than 500 injured in clashes between the supporters and opponents of the ousted president Morsi Wednesday overnight.
