Germany's Foreign Ministry has urged all political parties in Egypt to refrain from violence or threats of violence, and called on Egyptian authorities to allow an international organisation access to ousted Islamist president Mohamed Morsi. A ministry spokesman said:
All forms of political persecution would be extremely damaging for the future of Egypt.
We call for an end to the restrictions on Mr Morsi, and we also urge all political powers, in particular the leaders of the Muslim Brotherhood, to refrain from all forms of violence or threat of violence
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.
