Fighting erupted Friday across Egypt between supporters of Mohamed Morsy and their opponents, leaving more than two dozen people dead and hundreds more injured while raising fears of widening violence after the military ousted the country's first democratically elected president.
The violence came as Morsy's supporters held massive protests across the country, calling for his reinstatement, a counter to huge demonstrations among those celebrating his ouster.
At least 26 people were killed and more than 850 were injured in clashes across the country that at times pitted Morsy supporters against his opponents and the military, state-run media reported, citing the Ministry of Health and medical officials.
Among those killed were five Morsy supporters who were shot by the army in front of the headquarters of the Republican Guard headquarters, where Morsy was said to be detained, the Muslim Brotherhood's political wing -- the Freedom and Justice Party -- said.
The health ministry reported that at least two people were killed and 65 injured in clashes there. It did not detail the injuries that led to the deaths of the two.
State broadcaster Nile TV, citing an unnamed security source, said live ammunition had not been used against demonstrators and no one was hurt or killed.
The fighting broke out when Morsy supporters tried to storm the building, Nile TV said.
CNN's Reza Sayah, reporting from outside the building, said he had seen one body around which scores of Morsy supporters were huddled, some of them crying.
A few feet away, demonstrators faced off across a barbed-wire barricade behind which stood a line of soldiers who detonated flash grenades and fired tear gas in an apparent attempt to get the demonstrators to move away.
Many of them did just that, though thousands of others remained in defiance. Demonstrators could be seen carrying away a wounded man. Some demonstrators waved flags and held pictures of Morsy and vowed not to leave until the military returns Morsy to office.
By nightfall, clashes on a bridge near Tahrir Square began after a standoff that saw anti-Morsy demonstrators advance on his supporters, with both sides throwing rocks and shooting fireworks at each other as hundreds of people ran, according to video footage.
About 100 soldiers, backed by armored personnel carriers, rolled on to the bridge to separate the two sides and break up the fighting.
CNN's Ben Wedeman was reporting live near the bridge when soldiers unplugged his crew's camera and confiscated the equipment. Wedeman said an agreement subsequently was reached that the camera would be returned -- without the video footage.
The violence was the latest fallout following Wednesday's move by the nation's powerful military to remove Morsy.
Morsy had become the nation's first democratically elected president a year ago, but failed to fix the nation's ailing economy or improve its crime problems and was seen by many as increasingly autocratic.
Human Rights Watch has said he had continued abusive practices established by Hosni Mubarak, who was pushed out in a popular uprising in 2011 after three decades of iron rule supported by the U.S. government.
"Numerous journalists, political activists, and others were prosecuted on charges of 'insulting' officials or institutions and 'spreading false information,'" the rights group said.
Throngs of protesters filled Egyptian streets for days, calling for him to step down.
The president's supporters turned out at massive counter demonstrations. At times, the two sides clashed with deadly consequences.
On Monday, the army gave Morsy 48 hours to agree to share power or be pushed aside.
On Wednesday, the military rejected Morsy's conciliatory gestures as insufficient and announced its "road map" to stability and new elections.
Morsy and a number of leaders of the Brotherhood were arrested and may face charges over the deaths of protesters during clashes with Morsy's supporters, many of whom also died.
Moves spark outrage
Adly Mansour, head of the country's Supreme Constitutional Court, was sworn in Thursday as interim president.
He immediately dissolved Egypt's upper house of parliament, the Shura Council, and appointed a new head of intelligence, state TV said Friday.
