CAIRO — Security forces fired tear gas at a prison truck Sunday in an attempt to free a police officer from rioting detainees, killing at least 36 suspects rounded up during streets clashes between Islamist supporters of the country's ousted president and police, officials said.
The killed detainees were part of a prison truck convoy of some 600 people heading to Abu Zaabal prison in northern Egypt, the officials told The Associated Press. Detainees in one of the trucks rioted Sunday night 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.
