UN rights boss urges both sides in Egypt to step back from brink

GENEVA - United Nations High Commissioner for Human Rights Navi Pillay called on all sides in Egypt on Thursday to "step back from the brink of disaster" a day after hundreds were killed when security forces crushed Islamist protest camps.
Pillay, a former UN war crimes judge, said that the heavy toll pointed to "an excessive, even extreme use of force against demonstrators."
"There must be an independent, impartial, effective and credible investigation of the conduct of the security forces. Anyone found guilty of wrongdoing should be held to account," she said in a statement issued by her Geneva office.
