Jerusalem (Reuters): Israel 's military said on Wednesday it believes Syrian President Bashar al-Assad's forces still possess several tonnes of chemical weapons , issuing the assessment two weeks after a chemical attack that killed nearly 90 people in Syria.
Some local media reports quoted the briefing officer, who spoke on condition of anonymity in line with Israeli military procedure, as putting the amount at up to 3 tonnes .
The findings supported earlier testing by Turkish and British laboratories.
Israeli Defence Minister Avigdor Lieberman told Israel 's Yedioth Ahronoth newspaper on April 6 that he was "100 percent certain" that the attack was "directly ordered and planned by Assad ". He did not elaborate on how he reached that conclusion.
Syria has repeatedly denied it was behind the attack in Khan Sheikhoun. Assad was quoted as saying last week that Syria's military gave up all its chemical weapons in 2013 after the agreement made at the time, and would not have used them anyway.
Israel closely monitors the civil war in Syria, a northern neighbour. During the six-year conflict, Israel has largely stayed on the sidelines, carrying out occasional air strikes against what it says is the movement of weapons to Iranian-backed Lebanese Hezbollah militants.
