CAIRO (AP) - Egyptian police fired tear gas Sunday in an attempt to free a guard from rioting detainees, killing at least 36 as the country's military leader vowed to tolerate no more violence after days of clashes that killed nearly 900 people.
The deaths of the prisoners, captured during the fierce fighting in recent days around Cairo's Ramses Square, came as Gen. Abdel-Fatah el-Sissi also called for the inclusion of Islamists in the government. Meanwhile, security forces detained Muslim Brotherhood members in raids aimed at stopping more planned rallies supporting ousted President Mohammed Morsi - which the military-backed government says fuels the violent unrest.
The suspects killed were part of a prison truck convoy of some 600 detainees heading to Abu Zaabal prison in northern Egypt, security officials told The Associated Press. Detainees in one of the trucks rioted and managed to capture a police officer inside, the officials said.
Security forces fired tear gas into the truck in hopes of freeing the badly beaten officer, the officials said. The officials said those killed died from suffocating on the gas.
The officials spoke on condition of anonymity because they were not authorized to speak to journalists.
However, the officials' version of event contradicted reports about the incident carried by state media. The official website of Egyptian state television reported that the deaths took place after security forces clashed with militants near the prison and detainees came under fire while trying to escape. The official MENA state news agency also said the trucks came under attack from gunmen.
State media also said all those killed and the gunmen belonged to the Muslim Brotherhood, the organization that Morsi hails from. The officials who spoke to AP said some of the detainees belonged to the Brotherhood, while others didn't.
The differences in the accounts could not be immediately reconciled Sunday night.
The violence adds to the ever-rising death toll in days of unrest. On Saturday alone, clashes between Morsi supporters and police killed 79 people, according to a government tally released Sunday and carried by MENA. That raised the death toll for four days of unrest across the country to nearly 900 people killed. Some 70 police officers were killed in clashes with protesters or retaliatory attacks during the same period, according to the Interior Ministry.
The clashes began Wednesday when security forces dismantled two encampments in Cairo of Morsi supporters, who demanded his reinstatement. The military overthrew Morsi in a bloodless July 3 coup after millions took to the street demanding him to step down.
Egypt's military-backed interim government declared a state of emergency after Wednesday's clashes and imposed a curfew, turning the capital into a ghost town after 7 p.m. every night. The government also began taking harsher measures to crippling the Brotherhood.
