Syria on Wednesday launched a plan supported by Washington to rid the Middle Eastern country of legacy chemical weapons that were used against its people by forces under ousted leader Bashar al-Assad.

For decades, Assad ran a large-scale program for chemical weapons, the use of which killed and injured thousands during Syria‘s long-running civil war.

Despite Damascus’ signing onto the Chemical Weapons Convention in 2013 and declaring a 1,300-ton stockpile, prohibited use continued and the size of the program remains unclear.

An international taskforce backed by the United States, Germany, Britain, Canada, and France, among others, will track down all remaining elements of the program and destroy them under the supervision of the Organization for the Prohibition of Chemical Weapons, Syria‘s ambassador to the United Nations, Ibrahim Olabi, said in an interview.

As many as 100 sites in Syria need to be inspected to determine what toxic munitions remain and how they should be destroyed, OPCW experts have said.

It will require a time-consuming and costly operation to prevent the proliferation of weapons of mass destruction in a region fraught with conflict and political turmoil. The expanding US-Israeli war on Iran and broader regional security concerns will make the timing of the mission uncertain, but all the more necessary to prevent future use, officials said.

GOVERNMENT VOWS FULL ACCESS

Assad was overthrown in December 2024, and the new government under Syrian President Ahmed al-Sharaa has vowed to turn a page and eradicate banned chemical weapons and give inspectors full access.

The move shows that Syria has shifted from a country that was once concealing chemical weapons use to one that is “leading the resolve” to do away with them, Olabi said.

Several international investigations concluded that the nerve agent sarin, as well as chlorine and sulfur mustard gas, was used by the Assad regime, but never revealed the full extent of the clandestine program.

“We don’t know what’s remaining. It was a secret program,” Olabi said. “The job is on Syria to basically look for these things and then declare them.”

A diplomatic source, who spoke on condition of anonymity to discuss the sensitive matter, said the 100 sites could be anything from military bases to laboratories or offices.

“It will probably take many months if not years to get it done, and of course the current situation in the Middle East doesn’t help the process to move forward to the actual destruction of any remnants of Assad‘s chemical weapons program,” the source said.
