Almost 500 people arrested after last year's failed coup in Turkey have appeared in court accused of taking part in the plot.
The trial focuses on events at the Akinci airbase which it is alleged was the plotters' headquarters.
It is taking place in a purpose-built courtroom outside the capital Ankara.
The defendants face charges from attempting to assassinate the president to murder. As some arrived at court they were met by protesters chanting "We want the death penalty!"
