Turkish authorities have arrested 44 suspected supporters of exiled cleric Fethullah Gulen, who is accused of plotting to overthrow the government.
According to Anadolu news agency, the arrested included several top bureaucrats and police officers.
President Recep Tayyip Erdogan, who won polls last week, giving his party a parliamentary majority, sees Mr Gulen as a rival.
According to the BBC, European observers said violence and media restrictions marred the polls.
On Tuesday, left-wing magazine Nokta said two of its editors were charged with plotting a coup in the government's latest move against opposition media outlets.
Cevheri Guven and Murat Capan were arrested the magazine's criticism of the election results, including a cover which read: "The start of civil war in Turkey."
