In a new interview with AFP, Syrian President Bashar al-Assad says the United States, "hand-in-glove with the terrorists", "fabricated" the suspected chemical weapons attack that killed at least 87, including many children, in a rebel-held town.
"They are Al-Qaeda. They are Al-Nusra Front who shaved their beards, wore white hats, and appeared as humanitarian heroes, which is not the case".
On April 6, the United States had launched 59 Tomahawk cruise missiles at the Syrian military airfield in Ash Sha'irat in response to the alleged chemical weapon use in Idlib province.
"There was no order to make any attack, we don't have any chemical weapons, we gave up our arsenal a few years ago", he said.
The description appeared meant to corroborate the Syrian government's claims that all chemical-weapons attacks in the war have been carried out by militant extremists.
Eighty-nine people were killed and others injured in the April 4 gas attack in Idlib province.
However, since 2013, there have been continued allegations that chemicals such as chlorine and ammonia have been used against civilians in the ongoing civil war.
The fact finding mission was sent from the Organisation for the Prohibition of Chemical Weapons (OPCW) in The Hague to gather bio-metric samples and interview survivors, sources told Reuters on Thursday.
Assad's scenario was the Syrian government's second version of events in nine days.
Chemical weapons have been banished from civilized nations since WWI.
The Organization for the Prohibition of Chemical Weapons is investigating the attack.
Russia, a close ally of Syria, on Wednesday vetoed a UN Security Council resolution which sought to condemn the killings and call on the Assad regime to cooperate with an global investigation into the attack.
The U.S. attack became a tension point with Russian Federation this week as Secretary of State Rex Tillerson visited Moscow.
The Russian authorities have quietly confirmed today what we said previously: the hotline between the U.S. and Russian militaries in Syria is still suspended despite previous claims that the Russians had agreed to reinstate it.
But he said his forces had not been diminished by the USA strike.
China, which normally sides with Russian Federation on issues relating to Syria, abstained from the vote.
Lavrov repeated the Kremlin's condemnation of the USA missile strike in Syria and said Washington was seeking "excuses for regime change".
He called on the USA and Russian Federation to improve communication to avoid further confrontation after Russian Federation sharply criticized the US bombing of the Syrian air base. "These are not just member states of the UN Security Council, but the permanent member states of the UN Security Council", he told reporters on Friday.
