The Egyptian Interior Ministry announced that its bodies were able to identify the driver of the car that carried out the bombing in front of the "Oncology Institute" in downtown Cairo a few days ago, and said that he is a member of the rebel movement of the Muslim Brotherhood.
The ministry said in a statement that it was also able to identify elements of what it called the "cluster cell of the rebel movement" who planned the attack, and that it has liquidated 17 of them during raids hideouts in Fayoum, Helwan and Cairo.
The Interior Ministry confirmed in a statement carried by state television that Abdel Rahman Khaled Mahmoud, a member of the rebel movement is the bomber of the Institute of Oncology incident, the movement has denied - in a statement attributed to them - responsibility for the bombing.
The statement said that the genetic fingerprint of the body parts collected from the scene was matched with members of the family of Abdul Rahman Khalid, pointing out that the car that carried out the bombing, was traveling in the opposite direction by mistake until it reached the accident area.
The ministry said that the dead were involved in the bombing of the Institute of Oncology, which took place on Sunday evening in downtown Cairo, killing 20 people and injuring others.
According to the statement, two were killed in a clash in the area of Tabbin in Helwan, south of Cairo, and eight were killed in Etsa Fayoum, while seven were killed in the suburb of Sunrise in Cairo,
The Egyptian Interior Ministry talked about armed resistance during the raids, as well as the seizure of explosives and weapons.
In many cases, following previous bombings, the Interior Ministry announced the liquidation of gunmen, while opponents question its accounts, saying that the dead were often disarmed, some of them forcibly disappeared.
It was President Abdel Fattah al-Sisi who declared the bombing an act of "terrorism", after the Interior Ministry said in its first statement that the explosion was just a normal incident.
But the Interior Ministry's second statement, issued after Sisi's tweet, said a quantity of explosives in a car intended to carry out a terrorist attack had led to the explosion in front of the oncology institute.
