Magdy Awad, chairman of the local ambulance services, says the bombs went off behind a mosque in Tanta today, as people were celebrating the Festival of Sheikh el-Sayyed el-Baddawi, which draws massive crowds every year.
Most of the victims were wounded by flying shrapnel. An Egyptian security official says bomb squads were able to disarm a third explosive device placed near the mosque.
The official spoke on condition of anonymity because he was not authorized to talk to media.
