On Sunday, a 12 kilogram bomb blasted through Cairo's main Coptic house of worship, killing at least 25 people and injuring more than 40 others.
Coptic Christians make up about 10% of Egypt's population. The tragic attack on the Saint Mark's Coptic Orthodox Cathedral is "like an attack on the Vatican," a CNN correspondent noted.
It is the largest attack on the Coptic community in Egypt in years. In 2011, an attack on the Two Saints Church in Alexandria claimed the lives of 23 people.
Since the attack, many Muslims have spoken out against the attack, standing in solidarity with the Coptic Christian community.
"Lord have mercy on us"
Lives were taken, hearts were broken
On going against the Prophet's wishes
*Oh messenger of God, on your birthday they have killed those you have asked us to keep well*
