St Mark’s Cathedral is the “seat of Egypt’s Orthodox Christian church and home to the office of its spiritual leader, Pope Tawadros II.”
Muslim Brotherhood operatives have long hated Pope Tawadros and the Coptic Christians, blaming them for the toppling of the Muslim Brotherhood regime in 2013, and considering them kuffar harbi, infidels at war with Islam whose lives can, because of that war, be lawfully taken.
“The blast took place as a Sunday mass being held in the chapel was about to end and coincided with a national holiday in Egypt marking the birth of Islam’s Prophet Muhammad.”
The bomb seems to have been timed to maximize the carnage.
“St. Mark’s Coptic Orthodox Cathedral in Cairo bombed, killing dozens,” Associated Press, December 11, 2016:
CAIRO – A bombing at Egypt’s main Coptic Christian cathedral killed 25 people and wounded another 35 on Sunday, in one of the deadliest attacks carried out against the religious minority in recent memory.
The attack came two days after a bomb elsewhere in Cairo killed six policemen, an assault claimed by a shadowy group that authorities say is linked to the outlawed Muslim Brotherhood. Islamic militants have targeted Christians in the past, including a New Year’s Day bombing at a church in Alexandria in 2011 that killed at least 21 people.
Egypt’s official MENA news agency said an assailant lobbed a bomb into a chapel close to the outer wall of St Mark’s Cathedral, seat of Egypt’s Orthodox Christian church and home to the office of its spiritual leader, Pope Tawadros II. Egyptian state TV gave the casualty toll.
Witnesses said the explosion may have been caused by an explosive device planted inside the chapel. Conflicting accounts are common in the immediate aftermath of attacks.
The blast took place as a Sunday mass being held in the chapel was about to end and coincided with a national holiday in Egypt marking the birth of Islam’s Prophet Muhammad. Most of the victims are thought to be women and children.
An Associated Press reporter who arrived at the scene shortly after the blast saw blood-stained pews and shards of glass scattered across the chapel’s floor. Men and women wailed and cried outside….
There was no immediate claim of responsibility for Sunday’s attack.
Egypt has seen a wave of attacks by Islamic militants since the military overthrew President Mohammed Morsi, a freely elected leader who hailed from the Brotherhood, in 2013. Many of Morsi’s supporters blamed Christians for supporting the overthrow, and scores of churches and other Christian-owned properties in southern Egypt were ransacked that year….
