The Egyptian Ministry of Health today said the death toll from overnight clashes in different parts of Cairo was seven in addition to 261 injured.
The clashes occurred between security forces and supporters of Morsi, the country's first democratically elected president who was ousted by the army two weeks ago.
Nineteen people were wounded in clashes in the central Ramses area near Tahrir Square and on the main bridges over the Nile, emergency services chief Mohammed Sultan said.
The violence comes as US Assistant Secretary of State William Burns, the highest American official to visit Egypt following Morsi's ouster, urged Egyptian leaders yesterday to engage in dialogue and end violence, saying the country has a "second chance" at democracy.
