CAIRO -- Security forces and armed men clashed with supporters of Egypt's ousted president early yesterday, killing at least 65 people. The mayhem spotlights how a heavy hand is being used against protests demanding Mohammed Morsi's return to office.
In chaotic scenes, pools of blood stained the floor and bodies were lined up under white sheets in a makeshift hospital near the site of the battles in eastern Cairo. Doctors struggled to cope with the flood of dozens of wounded, many with gunshots to the head or chest.
It was the deadliest single outbreak of violence since the military ousted Morsi on July 3 and one of the deadliest in 2 1/2 years of turmoil in Egypt. It was not immediately clear if all the 65 killed were protesters or if residents who joined the fight against the march were among the dead. The Muslim Brotherhood said 66 Morsi supporters were killed in the Cairo violence.
The extent of the bloodshed pointed to a rapidly building confrontation between the country's two camps, sharply divided over the coup that removed Egypt's first freely elected president after widespread protests against his rule.
Authorities talk more boldly of making a move to end weeks of protests by Morsi's largely Islamist supporters. At the same time, the Islamists are growing more assertive in challenging security forces as they try to win public backing for their cause.
Saturday's clashes were sparked when pro-Morsi protesters sought to expand their main Cairo sit-in camp by moving onto a nearby main boulevard, only to be confronted by police and armed civilians -- reportedly residents of nearby neighborhoods. Police initially fired tear gas, but in ensuing clashes, the protesters came under gunfire.
Officials from Morsi's Muslim Brotherhood and their allies decried what they called a new "massacre" against their side, only weeks after July 8 clashes with army troops in Cairo that left more than 50 Morsi supporters dead.
U.S. Secretary of State John Kerry said he spoke to Egyptian authorities, saying it is "essential" they respect the right to peaceful protest. He called on all sides to enter a "meaningful political dialogue" to "help their country take a step back from the brink."
UN Secretary-General Ban Ki-moon also asked security forces to "act with full respect for human rights" and demonstrators to "exercise restraint."
