ANKARA, April 6 (Xinhua) -- Autopsy results show that chemical weapons were used during Tuesday's attack in Syria's Idlib, Turkish justice minister said on Thursday.

Speaking to reporters in the central Anatolian province of Kirikkale, Bekir Bozdag said examination was carried on three bodies taken from Idlib to southern Turkish province of Adana.

Turkish Health Ministry also said that evidence linked to sarin gas was found in the bodies of three Syrian victims.

The autopsies were conducted in the presence of representatives of the World Health Organization (WHO) and the UN Organization for the Prohibition of Chemical Weapons, according to the minister.

The three Syrians died in Turkey after being brought to the country for treatment following the suspected chemical gas attack in Idlib.

The test process was filmed and samples were collected both by WHO representatives and Turkish forensics experts for further examination.

The public prosecutor's office in Adana said in a statement that tests were conducted at the city's forensic institute under the supervision of the prosecutor's office.

Autopsy results will be further examined in The Hague after Turkey, the Health Minister Recep Akdag said.

More than 100 civilians were killed and 500 others, mostly children, were injured in Tuesday's attack in Idlib, according to the Syrian opposition health minister, Firas Jundi.
