Journalists hold placards as they demonstrate across the street from Egypt's embassy in central London, Wednesday, Feb. 19, 2014. The protest organized by the National Union of Journalists called for the protection of journalists in Egypt, where six have been killed and many more injured covering events on the streets of Cairo and the rest of the country. Others, including Al-Jazeera English acting bureau chief in Cairo Mohammed Fahmy, a Canadian-Egyptian, award-winning correspondent Peter Greste of Australia and producer Baher Mohamed, an Egyptian have been imprisoned.
