ANKARA, Feb 15 (Reuters) - Turkish police said they have arrested 78 people accused of creating fear and panic by "sharing provocative posts" about last week's earthquake on social media, adding 20 of them were being held in pre-trial detention. Turkey's General Directorate of Security said it had identified 613 people accused of making provocative posts, and legal proceedings had been initiated against 293. President Tayyip Erdogan's ruling party had said a law was needed to tackle false accusations on social media, and it would not silence opposition. The government has also blocked social media in the past. Within a week of the earthquake, some 6,200 items of false information and news were reported to the government, Altun added.
