ISTANBUL -- Turkish President Recep Tayyip Erdogan vowed Saturday to carry out harsh measures against alleged putschists, stressing he would seek to bring back the death penalty, during a mass rally on a bridge in Istanbul attended by hundreds of thousands.
"Those traitors will always be remembered with hatred," Erdogan said, adding that Turkey "never hesitates to crush the heads of those who betray."
He also pledged to "rip off the heads of these traitors first," referring to terrorists, in the speech, which was laden with Islamic references and strong criticism of the opposition.
Erdogan added that prisoners arrested in connection with the coup would now wear a "Guantanamo"-style uniform to court, referring to the controversial U.S. prison camp in Cuba.
The speech on the Bosporus Bridge, which was renamed Martyr's Bridge last year and was one of the main battlegrounds of the 2016 coup, took place in front of thousands of people waving Turkish flags.
Erdogan also took part in late-night commemorations in Ankara for those who died in the attempted coup, while opposition parliamentarians boycotted the event.
Earlier on Saturday in the capital, Turkey's main opposition party leader decried the government's failure to prevent last year's coup attempt and the ongoing crackdown on alleged coup supporters during a special session of parliament marking one year since the failed putsch.
Kemal Kilicdaroglu, the head of the center-left People's Republican Party, or CHP, took a swipe at the country's leadership by demanding that the officials who allowed the coup plotters to infiltrate "the most sensitive positions of the state" be held accountable.
The government has blamed last year's July 15 coup on U.S.-based preacher Fethullah Gulen, a one-time ally of the ruling Justice and Development Party, or AKP.
Gulen's followers were allegedly able to infiltrate the state bureaucracy and military to carry out the coup attempt, but Gulen has denied all involvement.
