From Fox News:
The ISIS terror group has claimed responsibility for two separate Palm Sunday bombing attacks at Coptic Christian churches in Egypt that have killed 37 people and injured more than 100.St. Mark's Cathedral is believed to have been founded in 60 A.D. St. Mark the Evangelist, the author of the Gospel of Mark.
The first blast happened at St. George church in the Nile Delta town of Tanta, where at least 26 people were killed and 71 others wounded, officials said.
Television footage showed the inside of the church, where a large number of people gathered around what appeared to be lifeless, bloody bodies covered with papers.
A second explosion was later reported at St. Mark's Cathedral in the coastal city of Alexandria, leaving at least 11 dead, and 35 injured. The attack came just after Pope Tawadros II -- leader of the Coptic Orthodox Church of Alexandria -- finished services, but aides told local media that he was unharmed.
