French intelligence services will provide proof in the coming days that Syrian President Bashar Assad's forces used chemical weapons in an attack on April 4, French Foreign Minister Jean-Marc Ayrault said on Wednesday.
"There is an investigation underway (by) the French intelligence services and military intelligence ... it's a question of days and we will provide proof that the regime carried out these strikes," Ayrault told LCP television.
"We have elements that will enable us to show that the regime knowingly used chemical weapons," he said.
Sarin or a similar banned toxin was used in an attack in Syria's Idlib province on April 4, killing nearly 90 people.
Findings by the Organization for the Prohibition of Chemical Weapons support the allegations, as do earlier tests by Turkish and British laboratories.
The British delegation said on Wednesday that the Organisation for the Prohibition of Chemical Weapons' Director General Ahmet Uzumcu said results of their analysis "indicate that sarin or a sarin like substance was used."
