In Egypt, thousands of Muslim Brotherhood supporters gathered in Cairo to demand that President Mohammed Morsi cleanse the judiciary.
The judges say Morsi has worked to weaken their independence and authority. But Morsi's supporters say the president is just trying to rid the judiciary of corruption.
Meanwhile, in Washington D.C., American Coptics gathered in front of the White House Thursday to demand justice for Egyptian Christians.
"We need justice! Obama, Obama, where are you?" said one demonstrator.
The protestors say the United States should do more to pressure the Egyptian government to protect the Christian minority from attacks.
They also urged Christians around the world need to pray and stand with them.
"We don't want to see what happened in other countries in the Middle East also happen in Egypt," one protestor said. "We need to come together as one and push to allow Coptic Christians to remain in Egypt. Again, they are the indigenous people of Egypt and they have a right to remain there."
Tens of thousands of Coptic Christians have fled Egypt in the past two years.
