EGYPT (BP) — As government investigators sifted through the scene of what has been called Egypt’s worst bombing attack against Christians in the nation’s history, Monday (Dec. 12) the families of those who were slain mourned and buried their dead.

On Dec. 11, at least 24 worshippers were killed and 49 wounded when an explosion ripped through the Church of St. Peter and St. Paul, also known as Al Boutrosya Chapel, during Mass in a suburb of Cairo. The chapel is next to the St. Mark’s Coptic Orthodox Cathedral, which is held by many as the spiritual center of the Coptic Orthodox Church.

An initial statement by Egyptian President Abdel Fattah al-Sisi claimed that a suicide bomber had conducted the attack. The Interior Ministry later released a picture Abu Dajjana al-Kanani, 22, an Islamist militant the government claimed carried out the attack. No group has taken responsibility for the bombing.

Sunday’s explosion was exceptionally powerful. It shattered the windows of the church building, was heard for miles away and reduced the inside of the structure to rubble. Security sources told local news outlets that the bomb contained at least 26 pounds (12 kg) of TNT. It exploded inside the chapel on the side traditionally used by women.

As a result, most of the victims were either women in their 20s or children. Many of the slain children were infants. The death toll is expected to rise as others, who are now in the hospital, succumb to their wounds.

Al Boutrosya Chapel is located in Abbysia, Cairo, in a sprawling compound that houses the headquarters of the Coptic Orthodox Church. Besides St. Mark’s Coptic Orthodox Cathedral, it is also the home of a theological seminary.

The government’s decision to hold a state funeral for those killed was criticized by the victims’ families, and several were incensed at being kept from those whom they had lost. During the funeral service led by Coptic Pope Tawadros II, with Sisi present, Tawadros II said the attack on the Copts was an attack on all Egypt, “not just a disaster for the church but a disaster for the whole nation.”

While state officials and ranking members of the Coptic Orthodox Church were given passes to attend the service, passes for family members were limited and had to be approved by both the government and the church. Family members were forcibly separated from the caskets by youth ushers known commonly as “scouts.” Others who protested against being kept from attending the funeral were arrested, according to local media reports.

Sunday’s attack is considered to be the deadliest bombing against Christians in Egypt, but only by a small margin. On Jan. 1, 2011, just after midnight, 23 people were killed in a bombing at Saints Church in Alexandria that took place just after a New Year’s Eve service.

Conflicting accounts claimed the Alexandria bombing was either the result of a suicide bomber or a car bomb placed at the entrance of the church building. No one has ever been apprehended for the incident. The government has all but closed the case.

On April 7, 2013, Coptic Christians attending a funeral service for four Copts killed two days earlier in an anti-Christian rampage were in turn attacked themselves by at least 200 Muslim rioters.

The incident, which started with a few dozen men pelting the mourners with stones, quickly escalated into a massive attack against Christians at St. Mark’s Coptic Orthodox Cathedral involving firearms, flash-bang grenades, tear gas, fire bombs and other improvised weapons, besides cars set ablaze. Police who were assigned to protect the complex did nothing to stop the attack. When back-up arrived, instead of fighting off the attackers, police joined the attack on the side of the rioters.

One Christian, Mahrous Hanna Ibrahim, reportedly died from gunshot wounds and one Muslim died after he fell off a security fence he was climbing to attack Copts.

Wagih Jacoub, a noted human rights activists, said he was dismayed at the church’s reaction to the bombing and the government’s refusal to protect Christians.

“I don’t care about three days of mourning, I care about protecting Christians,” he said.

Hostilities toward Christians, according to Jacoub, start in mosques and classrooms where Muslim youth are indoctrinated to hate Christians.

“They are taught Christians are nothing, that they have no rights,” he said. “So what do you expect them to do? You expect them to grow up and hate Christians.”
