Istanbul, February 6: Two people attacked Turkiye's largest courthouse before being shot dead on Tuesday in an exchange of fire that also left one other person dead and five wounded. Authorities alleged the assailants were part of an extremist organisation that had been largely inactive in recent years.

Interior Minister Ali Yerlikaya said the man and woman attacked a security checkpoint at the Caglayan courthouse in Istanbul, and then were killed in an exchange of fire. Authorities said that one other woman also was killed in the gunfire, and that three police officers and two civilians were wounded. Yerlikaya later said the attackers were alleged members of the Revolutionary People's Liberation Party-Front, or DHKP/C, a far-left group that is considered a terrorist organisation by Turkiye, the United States and the European Union. Turkiye Mourns Tens of Thousands Dead, Surrounded by the Ruins of Last Year's Earthquake

The Caglayan courthouse, also known as the Istanbul Justice Palace, is a huge and heavily guarded court complex in the Kagithane district. It was Europe's largest courthouse when it opened in 2011. Footage published by Turkey's state-run Anadolu news agency showed the assailants appearing to shoot at police before being gunned down in the building's forecourt, while bystanders ran for cover.

Private news agency DHA reported that the elder sister of the female attacker appeared as a defendant at the courthouse half an hour after the attack. She faced charges of membership in a terrorist organization and possessing dangerous materials. The justice minister said the Istanbul Chief Public Prosecutor's Office has opened an investigation. Tunc told journalists that the attackers had previously served jail terms for terror-related offences.

A witness to Tuesday's attack, Emre Ozyurt, said his “blood froze” as bystanders fled in fright. The attack took place the day that Turkiye commemorated the anniversary of an earthquake in the south that killed more than 53,000 people. “The Republic of Turkiye will continue to fight against all terrorist organisations and those who support them,” President Recep Tayyip Erdogan said at a commemoration ceremony in the city of Kahramanmaras. “I would like to pray for the soul of the injured person who lost their life.” Turkey Helicopter Crash: Two Pilots Killed, Technician Injured As Chopper Crashes in Gaziantep Province

Three People Killed in Alleged Extremist Attack in Turkey

In March 2015, the DHKP/C group took a prosecutor hostage at the same courthouse, demanding details about the police killing of a teenager during anti-government protests the previous year. Two gunmen died as police stormed the building, and the prosecutor later died of his injuries. The group also claimed responsibility for a February 2013 suicide bomb attack on the US Embassy in Ankara in which a Turkish security guard was killed and four other people wounded.
