Nearly 500 people are standing trial in Turkey's capital, Ankara, for their alleged roles in a failed coup attempt last July.
"They're charged with murder, violating the constitution and attempting to kill the president," NPR's Lauren Frayer reports from Turkey. "Most are military officers who were stationed at an airbase where fighter jets took off and bombed Parliament on the night of the attempted coup last summer."
The failed coup killed some 249 civilians and the government declared a state of emergency. Then, it suspended or fired about 150,000 people from their jobs, NPR's Peter Kenyon reported, and arrested more than 50,000. The crackdown has drawn criticism from human rights groups.
"Being tried in absentia is Fethullah Gulen, a cleric the government calls the plot's mastermind. He lives in the U.S. and denies any role," Lauren added.
Of the 486 facing charges now, 461 are currently imprisoned, 18 have been released with judicial supervision, and seven are on the run, the state-run Anadolu news agency reported.
Many of the suspects could face life in prison if convicted, according to The Associated Press.
Turkey doesn't have a death penalty, but as Lauren reported, "People shouted 'Bring back the death penalty!' as defendants filed into court, flanked by Turkish police and soldiers. Someone waved a noose over the crowd."
President Recep Tayyip Erdogan has floated bringing back the death penalty, though Peter reports that the European Union has warned that "such a move would kill off Turkey's bid to join the union."
Photos from outside the court on Tuesday showed a long line of defendants led into the courtroom with security forces clad in green berets and red vests gripping each by the arm.
There are other trials ongoing in Turkey related to the attempted coup, but as the BBC reports, this is the largest one yet. It's expected to continue until Aug. 19, Anadolu reported.
Speaking at an event to mark the first anniversary of the failed coup attempt, Peter reported that President Recep Tayyip Erdogan said, "We will not forget, (and) will not let it be forgotten. ... We do not learn the lessons from July 15, new July 15ths will be inevitable." Erdogan then vowed to "chop the heads off the traitors."
In April, a referendum that passed by a narrow margin radically expanded Erdogan's powers.
