The Guardian newspaper reports scores of Syria’s most prominent intellectuals and activists have gone into hiding as government forces continue to carry out raids and arrests across the country. Two former guests of Democracy Now! are now in hiding: Haitham al-Maleh and Razan Zeitouneh, both prominent Syrian human rights attorneys. Human rights organizations estimate the Syrian authorities have detained more than 7,000 people since protests began in mid-March. About 600 people have been killed. Meanwhile, a journalist with Al Jazeera named Dorothy Parvaz has been missing since Friday. Parvaz is an American, Canadian and Iranian citizen. She used to work at the Seattle Post-Intelligencer and was a Nieman fellow at Harvard University.
