Alaa Abd-El Fattah is a prominent Egyptian activist and blogger. Imprisoned in 2006 for 45 days by the Mubarak regime, he was also detained for more than two months by Egypt's military rulers at the end of 2011.
Nabeel Rajab is the head of the Bahrain Center for Human Rights. He has been detained on several occasions by the regime and is currently in prison after his arrest last Saturday.
Just before Rajab's detention, the two men were interviewed by Julian Assange for almost three hours --- Assange's organisation WikiLeaks has posted a full transcript.
