Supporters of deposed Egyptian president Mohamed Morsi are continuing to hold a mass sit-in at Cairo's Rabaa Al Adaweya mosque.
Thousands of people turned out to pray this evening at the end of the first day of Ramadan - the Islamic holy month of fasting.
Earlier, a spokesman for the Muslim Brotherhood accused Egypt's authorities of trying to break up the sit-in by issuing arrest warrants for some of the group's leaders.
He said that the warrants had not been acted on so far.
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.
