The injured were rushed to nearby hospitals, medical sources said.
The explosion took place outside the gate of the Church of St. Peter in the Cathedral complex, according to eyewitness accounts.
Security forces quickly set up a cordone around the blast site.
Maj. Gen. Khaled Abdel-Aaal, head of the capitals security directorate, arrived later to oversee the security operation.

The Cathedral is Cairo's main Coptic church and seat of the country's Coptic Orthodox pope. Egypt's Coptic Christians make up about 10 percent of the country's population.
