Staff members of Zaman newspaper hold placards reading "Free press can not be silenced" during a protest against a raid by counter-terror police in Istanbul on December 14, 2014. Turkish police launched a sweeping operation to arrest supporters of President Recep Tayyip Erdogan's rival, US-exiled imam Fethullah Gulen, including a raid on the offices of the Zaman daily, which is close to the cleric. A huge crowd gathered outside the offices of Zaman on the outskirts of Istanbul, creating a small stampede and forcing the police to leave the building without detaining any newspaper employees.
