Since Egypt's revolution began, tensions among Egypt's Muslims and Christians have only increased. Earlier this month, it once again turned deadly. Tit-for-tat killings left three Muslims and at least six Christians dead.
That and other religious violence is prompting a public debate about religious identity in Egypt. One group of young Egyptians wants to remove religious labels from national ID cards.
President Obama has been hosting a series of visitors from the Middle East, and all of them have been urging the U.S. to get more involved in Syria.
They have included the emir of Qatar, Sheik Hamad bin Khalifa Al Thani, whose country has been arming rebel forces in Syria. Obama wants to see such aid go to moderates — but that requires more cooperation with partners like Qatar. Problem is, they don't always see eye to eye.
