Turkish prosecutors said investigations had begun into nearly 350 social media accounts over posts about the fall of the Turkish lira against the U.S. dollar, the Sözcü newspaper said on Monday.

The Turkish lira has fallen to below 7 to the dollar from around 4.5 since U.S. President Donald Trump first announced sanctions against Turkey two weeks ago over to Turkey’s detention of American pastor Andrew Brunson and other U.S. citizens.

The Istanbul chief public prosecutor’s office said in a statement it was examining a total of 346 social media accounts on suspicion of “engaging in activities that threaten financial security”.

Turkish police said the investigations would centre on social media posts that aim to “form a negative perception of Turkey’s economy through dollar rate manipulation”.
