UPDATE 8:23 a.m. EST:
The explosion in the Alexandria church, the second to hit an Egyptian church Sunday morning, killed 11 people and injured at least 35 others, Egypt's Health Ministry said. Pope Tawadros II of the Coptic Church had celebrated Palm Sunday there earlier that day.
No one has claimed this attack either. However, in December, ISIS claimed responsibility for an attack on a Cairo church and vowed more attacks on Christians.
ORIGINAL STORY: A bomb exploded in a church near Cairo, Egypt on Sunday, killing at least 26 people and wounding at least 71 others, according to officials.
The attack in Tanta was the latest assault on Egypt's Christian minority, which is about 10 percent of the nation's population. Pope Francis is due to visit Egypt in just a few weeks.
Another bombing in a Coptic church in Alexandria also caused casualties, CNN reported. The head of the Coptic Church had celebrated at the Alexandria church earlier Sunday.

Officials reported a second explosion in Alexandria shortly after the initial bombing.
Grand Sheikh Ahmed el-Tayeb, head of the leading center of Sunni Islam learning, decried the incident as a "despicable terrorist bombing that targeted the lives of innocents." Pope Francis offered his condolences to the victims as well.
French President Francois Hollande also decried the attack and said France stood in solidarity with Egypt.
No one has claimed responsibility for the attack, which took place on Palm Sunday, a Christian holiday that marks the beginning of Holy Week that culminates in Easter.
Nearby mosques were converted into first-aid centers for victims.
