Egypt's Muslim Brotherhood said on Thursday it would bring down the "military coup" but stressed it remained committed to a peaceful struggle, despite the heavy loss of life when government forces broke up its protest camps.
Meanwhile, Egyptian authorities cleared remains of a sit-in by Mursi's supporters in Cairo's Nasr City neighborhood after Wednesday's deadly army raids on Mursi supporters, killing hundreds.
The crackdown on Wednesday defied Western appeals for restraint and a peaceful, negotiated settlement to Egypt's political crisis following the military's removal of Islamist President Mohamed Mursi last month, prompting international statements of dismay and condemnation.
Security forces struggled to clamp a lid on Egypt after the worst nationwide bloodshed in decades, although a curfew largely held in Cairo overnight.
