Israeli Defense Minister Avigdor Lieberman has accused Syrian President Bashar Assad of directly ordering a chemical attack on the Idlib province using the country's air force.

The Syrian National Coalition of Revolution and Opposition Forces reported that some 80 people were killed and 200 injured on Tuesday in a chemical weapon attack in the town of Khan Shaykhun in Idlib, blaming the Syrian army for the incident. A source in the Syrian army later told Sputnik that the army did not have chemical weapons and the allegations could be part of anti-Damascus propaganda.

"The two deadly chemical attacks on civilians in Syrian Idlib province and a local hospital were planned and carried out on the direct order of Syrian President Bashar Assad with the use of Syrian planes," Lieberman told the Yediot Ahronoth newspaper, adding that he was "100 percent certain about it."
