United Nations (United States) - AFP
The report of a UN committee confirmed on Thursday the responsibility of President Bashar al-Assad's regime for a deadly attack by sarin gas on the Syrian city of Khan Sheikun in last April .
"The Commission is confident that the Syrian Arab Republic is responsible for launching the Sarin gas on Khan Sheikhan on April 4, 2017," said the joint report of the United Nations and the Organization for the Prohibition of Chemical Weapons (OPCW).
"The Sarin gas was fired by a bomb dropped by an aircraft," it said.
The Committee pointed out on the other hand that the elements of the "Daash" used the mustard gas in an attack on the area of Umm Hawash in northern Aleppo in September 2016.
The attack on sarin gas on the town of Khan Sheikun in Idlib province, which was controlled by fighters of the opposition factions and jihadists, killed 83 people, according to the United Nations, while the Syrian Observatory for Human Rights killed at least 87 people, including thirty children.
In response to Khan Shikhun's attack, two US ships in the Mediterranean Sea on the sixth night of April 7 fired Tomahawk cruise missiles at the air cap base in central Syria.
From this base, according to Washington, the chemical attack on Khan Sheikhan was launched.
United Nations experts have recently gone to Al Qaeda to prepare their report.
The United States, France and Britain accuse Syrian President Bashar al-Assad of responsibility for the attack on Khan Sheikhan, but Damascus denies any involvement.
Russia insists the sarin gas attack on Khan Sheikun was probably caused by a ground bomb and that it was not carried out by a Syrian air attack, as the West claims.
Earlier, the Organization for the Prohibition of Chemical Weapons (OPCW) confirmed the use of sarin in the April attack, but did not have the authority to determine who was responsible for the attack.
The new report came two days after Russia vetoed the UN Security Council on Tuesday to extend a one-year mandate to investigate the body behind chemical weapons attacks in Syria.
US Ambassador to the United Nations Nicky Hailey welcomed the findings of the new report and said the UN Security Council should send a "clear message" that the use of chemical weapons should not be tolerated.
"Ignoring the huge number of evidence in this case shows a deliberate disregard of widely agreed international standards," Hayley said in a statement.
"The Security Council must send a clear message that the use of chemical weapons will not be tolerated ... and must fully support the work of impartial investigators."
British Foreign Secretary Boris Johnson said the new report had reached a "clear conclusion", calling for "the international community to unite in order to hold the Assad regime accountable."
"I call on Russia to stop covering up its abhorrent ally and to keep its commitment to ensure that chemical weapons are never used again.
