Egypt's weakened Muslim Brotherhood is calling out for nationwide protests on Friday. It's the latest attempt to pressure the reinstatement of ousted President Mohammed Morsi.
Essam el-Erian, a top official of the Brotherhood, is urging people to rise against what he called a "failed, bloody military regime."
The government is on high alert and says it is ready to deal firmly with any attempts to attack governmental or religious institutions.
Last Friday, the Brotherhood also called for protests with a disappointing turnout.
