ISTANBUL (AP) — Turkish state media say a court has ordered that 10 Syrians with suspected links to the suicide bomber who killed 10 Germans, be jailed pending trial over possible membership in a terror group.

The 10 were among 17 Syrians who were referred to an Istanbul court on Sunday for questioning. TRT television says six others suspects were released on bail. Proceedings against the 17th suspect — a minor — were ongoing.

The suicide bomber set off the explosion near a group of German tourists on Tuesday, just steps away from the landmark Blue Mosque, killing 10 of them.

Turkish officials say the Syrian bomber was affiliated with the Islamic State group. No group has claimed the attack.

There was no information on the suspects or their links to the bomber.

This story has been corrected to show that the minor was among the 17 suspects referred to in court, not an 18th suspect.
