Mikhail Uliyanov, the head of the Russian Foreign Ministry's department for Nonproliferation and Arms Control (DNAC) said earlier on Thursday that the OPCW inaction over chemical weapons incident could damage its credibility as there are no facts that OPCW representatives have visited the Khan Sheikhoun area.
Israel, along with the United States and much of the worldwide community, have accused Assad's forces of carrying out the attack.
"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 France's LCP television.
In response to the attack, the USA fired 59 missiles at the Syrian air base said to be the launching pad for the chemical attack.
Israel has largely stayed out of the civil war raging in its northern neighbor.
While the amounts of chemical weapons Assad kept weren't known, OPCW continued reporting on the use of chemical weapons by the regime, even some which Assad had pledged to surrender.
The United States and many other nations have called the attack a chemical weapons attack and accused the Syrian government of responsibility. Lets pray for President Donald Trump as he faces the North Korean Kim Jong-un with his growing uranium addiction and a program to reach the US with his nuclear armed rockets.
The US warned Moscow via a pre-established military-to-military communications channel in advance of its April 6 cruise missile strike in order to prevent any Russian casualties.
The U.S. -led coalition has targeted ISIS munitions depots and weapon-manufacturing sites with airstrikes in Iraq and Syria.
A senior military official told reporters that the Israeli intelligence estimates that Assad has "between one and three tons" of chemical weapons.
United States missile attack on Syrian airbase Targeted attack or accident? Syria agreed to give up its chemical weapons arsenal in 2013. But doubts began to emerge soon afterward that not all such armaments or production facilities were declared and destroyed. Inquiries confirmed the attacks at Ghouta back in August 2013 released sarin on a relatively large scale, but the perpetrators have never been formally identified.
Images from the attack on Khan Sheikhoun on April 4 showed victims limp, with pinpoint eyes and frothing mouths, as emergency responders rushed to strip clothes from bodies and hose away chemical substances.
