The state of emergency will last for three months, according to Egyptian President Abdel Fattah el-Sisi.
The attacks, which were claimed by ISIS, follow warnings by the terrorist group that it would escalate attacks on Egypt's Christians, who the CIA estimates make up roughly 10 percent of the country's population.
The two bombings Sunday killed at least 44 people and injured at least 126 others, according to Egyptian officials. The first exploded in a Coptic Christian church in the Nile Delta town of Tanta, and the second several hours later at Saint Mark's Cathedral in the coastal city of Alexandria, the historic seat of Christendom in Egypt.
ISIS claimed that the blasts were the work of suicide bombers who detonated explosive vests at the churches. [ABC News] Read more
