"Thousands of demonstrators clash with security forces on Tuesday outside Egypt's presidential palace demanding President Mohamed Morsi step down. The protests were triggered by the president's call for a referendum on what opponents call an illegitimate draft constitution. Morsi ignited a storm of unrest in his bid to prevent the judiciary from derailing a troubled political transition."
