PARIS, April 26. /TASS/. France has evidence proving the use of sarin gas in the chemical attack carried out in Syria’s Idlib Governorate on April 4, French Foreign Minister Jean-Marc Ayrault said on Wednesday.

According to Jean-Marc Ayrault, Bashar al-Assad’s regime is responsible for the chemical attack carried out in the Idlib Governorate. 

"The samples that the French intelligence collected have shown that sarin gas was used during the chemical attack," he said. "When the samples were compared with those collected after previous attacks, it showed that this poisonous substance was produced in a Syrian laboratory," the diplomat added.

The alleged chemical weapons incident in the town of Khan Shaykhun, the Idlib Governorate, occurred on April 4, killing more than 80 people.

According to the Russian Defense Ministry, on April 4, the Syrian air force delivered airstrikes on several militant facilities where munitions filled with poisonous substances were being made. However, Washington came to the conclusion that Damascus had used chemical weapons which led the US to carry out a missile attack on a Syrian military air base located in the Homs Governorate on April 7, as the US believes that the attack on Khan Shaykhun was launched from there.
