BEIRUT (AP) — Syria's government has harshly criticized the international chemical weapons watchdog probe that concluded sarin gas was used in a deadly attack in Syria, saying it relied on the testimonies of "terrorists" and was false.

Syria's Foreign Ministry in a statement Saturday called on the Organization for the Prohibition of Chemical Weapons to prepare "impartial and credible reports thart have not been subjected to extortions by countries and parties that prevent it from reaching the truth." The ministry calls the findings "the creation of a sick mind."

The findings released Friday concluded that sarin nerve gas was used in the April 4 attack on Khan Sheikhoun in Idlib province, killing more than 90 people, including women and children. But the report stopped short of assigning responsibility.
