Hundreds were wounded in addition to the half-dozen killed by a series of explosions outside police headquarters in central Cairo on Friday morning.
A powerful car bomb exploded outside the police headquarters in central Cairo on Friday morning, killing four people and wounding at least 76.
Hours later, there were three more blasts elsewhere in the city, killing two people and injuring several more.
The attacks come on the eve of the third anniversary of the 2011 uprising.
The revolution forced the country’s decades-long ruler Hosni Mubarak to resign.
An al-Qaeda-inspired militant group Ansar Beit al-Maqdis (Champions of Jerusalem) has said it carried out the attack on the police headquarters.
The group previously claimed responsibility for a car bomb attack on a security building in the northern city of Mansoura in December that killed 16 people and injured more than 100 others.
The authorities blamed the Muslim Brotherhood for that attack - something the group strongly denied - and declared it a terrorist group shortly afterwards.
