The terror group claimed responsibility for two Palm Sunday bombing attacks at Coptic Christian churches in Egypt that killed 37 people and injured over 100.
The town of Tanta on the Nile Delta was where the first bombing took place, killing 26 and injuring 71 others, according to officials.
A second bombing was later reported in Alexandria where at least 11 are dead and 35 injured, but the death toll may rise based on the seriousness of the injured.
Initially, no one claimed responsibility for the attacks that come a week before Easter.
Ahmad Deif, provincial governor told state-run Nile TV channel that "Either a bomb was planted or someone blew himself up."
The Tanta attack was the last in a series of attacks on Egypt's Christian minority, which accounts for 10 percent of the population. They are repeatedly targeted by Islamic extremists because parts of the Qu'ran ask Muslims to wage war against Christians and Jews, "wherever you find them."
Pope Francis is due to visit Egypt in a few weeks.
Grand Sheikh Ahmed el-Tayeb who heads Egypt's Al-Azhar, a leading center of learning in Sunni Islam, condemned the attack. He called it a "despicable terrorist bombing that targeted the lives of innocents."
Unfortunately, certain parts of the Qur'an do not see Christians and Jews as 'innocent' and thus, are fair game for their bloodlust.
One local ISIS affiliate claimed a suicide bombing in a Cairo church that killed 30 people, mostly women, and a string of killings in the Sinai Peninsula. The group is threatening more attacks.

Christians are fleeing to safer places just as the Jews had to flee most of the Middle East in order to survive the rampant anti-Semitism as seen in certain parts of the Qur'an.

Ever since Mohamed Morsi was overthrown in 2013, Egypt has experienced a wave of Islamic attacks inspired by certain parts of the Qu'ran.
