BEIRUT — Turkey said today that autopsies of Syrian victims from this week’s assault in Syria’s Idlib province show they were subjected to chemical weapons as France’s foreign minister called for the prosecution of President Bashar Assad’s government amid growing international outrage over the assault that activists say killed 86 people.

Damascus maintains it didn’t use chemical weapons, instead blaming the rebels for stockpiling the deadly substance.

In Turkey, state-run Anadolu and the private DHA news agencies quoted Justice Minister Bekir Bozdag as saying that “it was determined after the autopsy that a chemical weapon was used.”

Turkish officials say that close to 60 victims of the attack were brought to Turkey for treatment and three of them died.
