As protesters clashes, President Mohammed Morsi of Egypt announced a referendum on a proposed constitution. NBC's Jim Maceda reports.By NBC News staff and wire servicesCAIRO - Protests by Islamists allied to President Mohamed Morsi forced Egypt's highest court to adjourn its work indefinitely on Sunday, intensifying a conflict between some of the country's top judges and the head of state.
The Supreme Constitutional Court said it would not convene until its judges could operate without "psychological and material pressure," saying protesters had stopped the judges from reaching the building.
Several hundred Islamists had protested outside the court building ahead of a session in which it was due to examine cases against the legality of the upper house of parliament and the assembly that drafted the new constitution, both bodies dominated by Islamists.
