Egypt's ElBaradei says uprising "cannot go back"

CAIRO Jan 30 (Reuters) - Egyptian opposition leader Mohamed ElBaradei told thousands of protesters in central Cairo on Sunday that an uprising against Hosni Mubarak's rule "cannot go back".

"You have taken back your rights and what we have begun cannot go back," he told cheering crowds who responded "down with Mubarak". "We have one main demand -- the end of the regime and the beginning of a new stage, a new Egypt."

"I bow to the people of Egypt in respect. I ask of you patience, change is coming in the next few days," he said.
