A Turkish court on Sunday ordered the arrest of four suspects in relation to the deadly Ankara blasts last week.
Eleven people detained over the twin suicide bombings that hit the Turkish capital on Oct. 10 were sent to the courthouse earlier on Sunday, according to judicial sources.
The prosecutors decided to refer six of them to the penal court on duty, while releasing four others and requesting judicial controls for another.
Fourteen suspects had been taken into custody as part of the investigation. Three among them - who were detained due to suspicious posts on Twitter - were released earlier, the judicial source told Anadolu Agency.
The suicide bombings at a peace rally on Saturday last week have claimed 102 lives and injured hundreds of others.
The blasts have shaken Turkey as the country faces a general election re-run on Nov. 1, while counter-terrorism operations continue in the southeast and an ongoing civil war rages on in Syria nears the southern border.
