CAIRO (AP) — Egypt’s Muslim Brotherhood called for a wave of protests Friday, furious over the military’s ouster of its president and arrest of its revered leader and other top figures, underlining the touchy issue of what role the fundamentalist Islamist movement might play in the new regime.

There are concerns of Islamist violence in retaliation for Mohammed Morsi’s ouster, and some former militant extremists have vowed to fight.

Suspected Islamic militants opened fire at four sites in northern Sinai, targeting two military checkpoints, a police station and el-Arish airport, where military aircraft are stationed, security officials said. The military and security responded to the attacks, and one soldier was killed and three were wounded, according to security officials who spoke on condition of anonymity because they were not authorized to speak to reporters.

The question of the role of the Brotherhood has long been at the heart of democracy efforts in Egypt. President Hosni Mubarak, ousted in 2011, and previous authoritarian regimes banned the group. After Mubarak’s fall, the newly legalized group vaulted to power in elections, and its veteran member Morsi become the country’s first freely elected president.

Now the group is reeling under a huge backlash from a public that says the Brotherhood and its Islamist allies abused their electoral mandate. The military forced Morsi out Wednesday after millions of Egyptians turned out in four days of protests.

Adly Mansour, the head of the Supreme Constitutional Court, with which Morsi had repeated confrontations, was sworn in as interim president.

In his inaugural speech, broadcast nationwide, he said the anti-Morsi protests that began June 30 had “corrected the path of the glorious revolution of January 25,” referring to the 2011 uprising that toppled Mubarak.

The Brotherhood charged the military staged a coup against democracy and said it would not work with the new leadership. It and harder-line Islamist allies called for a wave of protests Friday, naming it the “Friday of Rage,” vowing to escalate if the military does not back down.

Brotherhood officials urged their followers to keep their protests peaceful. Thousands of Morsi supporters remained massed in front of a Cairo mosque where they have camped for days, with a line of military armored vehicles across the road keeping watch.

“We declare our complete rejection of the military coup staged against the elected president and the will of the nation,” the Brotherhood said in a statement, read by senior cleric Abdel-Rahman el-Barr to the crowd outside the Rabia al-Adawiya Mosque in Cairo.Read the full story here.
