Egypt's Coptic Christians are observing three days of fasting and prayer for victims killed in this weekend's protests.
At least 25 people died when police attacked hundreds of Christian protestors in Cairo.
Christians there are angry that police don't do more to protect them from radical Muslims.
CBN reporter Gary Lane said police attacks against Christians are becoming more frequent.
"This isn't the first time this has happened -- where the army has attacked Christians," Lane said. "(It) happened in January; they attacked a monastery. I went there and and reported on that."
"Also in March (in) Macatum, which is part of Cairo, 11 Christians were killed in that attack, so I'm afraid this is not the last that we've seen," he said.
The White House released a statement saying the rights of Egyptian Copts to worship and protest must be respected.
