The Organization for the Prohibition of Chemical Weapons (OPCW) has strongly condemned Syria's Bashar al-Assad regime over using chemical weapons for the first time after its three-year-long violations.
Despite the Syrian regime's denials, it was proved more than once by the independent commissions that Assad had been using chemical weapons since 2013.
In its statement that made on Friday, OPCW condemned Daesh over using chemical weapons along with the Assad regime.
The OPCW-U.N. mission found that the Syrian government carried out three toxic attacks in March and April of last year, while Daesh terrorists had used sulphur mustard gas.
"There is a clear determination across the international community to hold those who have used these heinous weapons to account," said British Foreign Minister Boris Johnson in a statement responding to the vote.
The findings set the stage for a U.N. Security Council showdown between the five veto-wielding powers, likely pitting Russia and China against the United States, Britain and France over how those responsible for the attacks should be held accountable.
The condemnation from OPCW came years after the Assad regime's chemical attack which was used against the moderate opposition, children and women in 2013 in East Ghouta for the first time.
The delay is also related with the indecisive policy of U.S President Barack Obama, as he didn't take the necessary steps against the Assad regime despite previously describing chemical weapon usage as a 'red line'.
Instead of intervention in Syria, Obama signed an agreement with the Russia-backed Assad regime which he believed will pave the way of the extradition of chemical weapons from Syria.
Despite the signed agreement, the Assad regime was discovered to have used chemical weapons several more times.
In this time period, the international community only condemned the move of Assad while OPCW didn't take any step against the situation.
The civil war in Syria has killed more than 250,000 people, according to the United States while the Syrian Center for Policy Research, an NGO, has put the total death toll from conflict at more than 470,000.
