SINCAN: Nearly 500 people appeared in court Tuesday in the biggest trial yet of suspects from Turkey's failed coup, facing charges of conspiring to oust the government from an air base seen as the plotters' hub, reports AFP.

A total of 486 suspects have been indicted in the case and almost all the suspects -- a total of 461 -- are held in custody while seven are still on the run and the remainder charged but not in jail.

Some of those held were marched into the court outside Ankara one-by-one in a long line in front of the television cameras and public, with each suspect held by two members of the Turkish gendarmerie and flanked by an armed soldier.

People chanted "we want the death penalty!" and some threw nooses towards the suspects. The death penalty has been abolished in Turkey since 2004.

There were also chants of "martyrs don't die, the nation won't be divided". Some people threw water bottles, an AFP reporter said.

The suspects are accused of running the coup bid from the Akinci air base northwest of the capital, which the authorities regard as the headquarters of the plotters where orders were sent out for fighter jets to bomb parliament.

They are charged with crimes ranging from murder, violating the constitution and attempting to kill President Recep Tayyip Erdogan.

If convicted, they face life imprisonment.

Among the main suspects named in the indictment but still on the run is US-based Muslim cleric Fethullah Gulen, who is accused of ordering the attempted July 15 putsch.

Gulen, who is based in a secluded compound in the US state of Pennsylvania, strongly denies the charges.
