Police has managed to defuse another bomb planted in a public transport bus at al-Hegaz Square in Heliopolis, state-run agency MENA reported.
A security source said the bus was empty, adding that civil defense agents are combing the area to ensure no more detonative devices are present.
The discovery comes two days after a bomb exploded Thursday in a bus in Nasr City, injuring five, while police defused another one in the same area near Al-Azhar University.
A third bomb was defused outside Kafr al-Sheikh Security Directorate on the same day.
