Turkish prosecutors are investigating dozens of people for "provocative" social media messages about the deadly earthquake in eastern Turkey, reports said on Monday.

The death toll from Friday's quake in Elazig province had reached 39 people as hopes dimmed of finding more survivors amid the rubble.

The Ankara prosecutor's office is checking 50 individuals on suspicion of "spreading fear and panic" and "insulting the Turkish people, the Turkish republic and the state institutions", the Hurriyet daily said.
