A symposium was held in New York on the sidelines of the assassination of Saudi journalist Jamal Khashoggi entitled "Human Rights and Freedom under Siege in Saudi Arabia" on the sidelines of the 74th session of the United Nations.

The UN Special Rapporteur on arbitrary executions, Agnes Kalamar, Khadija Genghis, fiancée of the late Khashoggi, Lina al-Hathloul, sister of Jane al-Hathloul, detained in Saudi Arabia, and Abdullah al-Odah, son of Saudi preacher Salman al-Awdah, detained in Saudi Arabia.

The UN rapporteur on extrajudicial executions, Agnes Kalamar, said the Saudi crown prince's acknowledgment of his responsibility as governor for Khashoggi's death was insufficient and not credible.

Khashoggi's fiancee, Khadija Genghis, said the crown prince's claim that the killing was not his knowledge was a political maneuver, while Kalamar said confession without action was not credible.

"The same minds who brutally murdered Khashoggi are trying to endorse the death penalty in an attempt to kill my father through the judiciary," Abdullah al-Awda, son of preacher Salman al-Awda, said during the seminar.

Lina al-Hathloul, sister of activist Jane Hathloul, said that Saudi Arabia has already become a "police state. There is no room for freedom of thought, there is no room for freedom of expression and decisions are taken only by the authority."

Turkish President Recep Tayyip Erdogan has pledged before the United Nations General Assembly to continue to investigate the Khashoggi case.

According to Al Jazeera correspondent, a number of American activists also gathered in front of a conference organized by a Saudi institution on the sidelines of the meetings of the Assembly, as part of a continuous protest campaign to remind his case with the anniversary of his death.

The UN special rapporteur on extrajudicial executions, Agnes Kalamar, had earlier asked the CIA to disclose secret data in her possession relating to Khashoggi's murder. To achieve justice for Jamal Khashoggi requires patience, time and exposures of lies.
