Three U.S. senators are urging the State Department to respond to attacks against Christians in Egypt.
Sen. Roy Blunt, R-Mo., and Tennessee Republican Sens. Lamar Alexander and Bob Corker co-signed a letter to the State Department urging the administration to press Egypt's interim government to step up protection of its Christian population.
A drive-by shooting Sunday on a wedding party outside a Cairo church left four dead, including two young girls.
Reports that Egyptian authorities are not doing enough to protect them are especially troubling.
The senators say increasing attacks have endangered the Christians' ability to worship. They want the administration to urge the military-backed Egyptian government to protect Coptic Christian churches, communities, and individuals.
"It is our view the Egypt is part of a broader trend: religious freedoms throughout the Middle East and South Central Asia, particularly for Christians, are under assault. The U.S. must respond to this challenge and continue to be a forceful defenders of religious freedom throughout the world," the trio wrote.
Since the ouster of Islamist President Mohammed Morsi, dozens of Coptic churches have been burned and the Coptic minority is constantly attacked by Muslim insurgents.
