Egypt's El Baradei arrives in Egypt

Mohamed El Baradei, the former head of the UN nuclear watchdog turned Egyptian reform campaigner, arrived in Cairo on Thursday after saying it was time for President Hosni Mubarak to quit.

El Baradei, 68, arrived from Vienna, where he lives, to join a growing wave of protests against Mubarak inspired by Tunisia's overthrow of their authoritarian president. (Reuters)
