On Twitter, Egyptian Hani Shukrallah observes:
Interesting, the one common chant in Tahrir & #MB 's Rabaa is anti-US – a triumph of American policy!

Tahrir Square, in downtown Cairo, is the epi-centre of the Egyptian revolution. On June 30, Egyptians gathered there again to demand  that president Mohamed Morsi, a Muslim Brotherhood (MB) candidate, steps down. On July 3, Morsi's one-year reign was cut short  and an interim government now runs Egypt. Morsi's supporters have since been staging a sit-in in Rabaa, also in Cairo, to protest his ousting.
