Thousands gather outside the Presidential Palace in Cairo.
They are still outraged over President Mohamed Mursi's decision to expand his powers.
Officials say the unrest prompted the Islamist president to leave the building.
Mursi ignited a storm of unrest in his bid to prevent a judiciary still packed with appointees from the former regime from derailing a troubled political transition.
Familiar sounds on the street as demonstrators call for change.
(SOUNDBITE) (Arabic) DEMONSTRATOR, ISRAA WAFID, SAYING:
"He has made himself a fort and he says it is a temporary fort - I don't believe it. We've spent 30 years being betrayed - we won't believe Mursi. He will remain seated in the chair and not leave it - the Brotherhood have always wanted to reach this point."
Mursi is facing the gravest crisis of his six-month-old rule. He's shown no sign of buckling under the pressure.
Protests go into the night. A sign that demonstrators are also not giving up the fight.
