The bodies of six protesters killed during November's Mohamed Mahmoud Street clashes remain unclaimed, according to assistant chief pathologist Ashraf Refaei.
A 15-year-old girl named Salsabil and a male named Ali Abdel-Monem Soliman are among the six.
A funeral service took place last June to bury 19 victims who had not been claimed for more than four months from the morgue by relatives.
The Mohamed Mahmoud Street clashes took place in November between anti-military council protesters and security forces, and left 45 martyred.
Violence erupted when police forcibly dispersed a sit-in in nearby Tahrir Square that was calling for an end to military rule and justice for those killed during the 2011 uprising that toppled Hosni Mubarak.
