The United States has called for the release of ousted Egyptian president Mohamed Morsi, who has been held in custody by the army since last week.
Thousands of Muslim Brotherhood supporters today took to the streets of Cairo to demand Morsi's reinstatement.
ITV News Middle East Correspondent John Ray reports.
The Muslim Brotherhood tells ITV News they are against violence but will "pay the price of their blood" to restore their ousted president.
Egypt's army has named two further officials in the transitional government as its supporters and opponents vowed to stay on the streets.
There has been outrage in Egypt after 51 people were killed near an barracks where ousted President Mohamed Morsi is thought to be held.
