Istanbul Public Prosecutor’s Office has issued detention warrants for 243 military personnel over their alleged use of ByLock, a smartphone messaging application which the government claims to be the top communication tool of the Gülen movement, on Wednesday.

The government accuses the movement of organizing a coup attempt on July 15 while the latter denies any involvement.

Police in 54 provinces were ordered to carry out simultaneous operations to detain 243 suspects early Wednesday.

In the very aftermath of the July 15 coup attempt, Turkey announced a State of Emergency, under which basic human rights came under jeopardy. More than 123,500 people lost their jobs, over 88,000 were detained and some 42,400 arrested in post-coup government purges.
