Mohamed ElBaradei, Egyptian presidential hopeful and opposition figurehed, told the Guardian newspaper, he was ready to do "whatever it takes" to save Egypt from deepening crisis.
"I think what we've seen today is an excessive use of force, bordering on a slaughterhouse, against innocent civilians exercising their inalienable right to demonstrate," ElBaradei told the Guardian.
ElBaradei added: "It's yet another indication that Scaf and the current government are failing to govern and I fully sympathise with the increasing calls coming from different quarters, including Tahrir, for a new government of national salvation that represents all shades of Egyptian society, one with full power.
"I will do anything to save the country from falling apart and what we are seeing right now is the country going down. People are calling on me to present this government, and I will do whatever it takes to save our country from falling apart."
