Yesterday was the first anniversary of the arrest and incarceration of three al-Jazeera journalists in Cairo. Peter Greste, Mohamed Fahmy and Baher Mohamed were charged with broadcasting false news and aiding a 'terrorist organisation' (the Muslim Brotherhood). Al-Jazeera rejects the charges. 'They’re not terrorists, they’re journalists,' Lindsey Hilsum, the Channel 4 News international editor, told me at a protest outside the Egyptian embassy in London. 'Everybody knows that. President El-Sisi knows that. It’s completely insane that they’re still in prison.'
