The Organization for the Prohibition of Chemical Weapons (OPCW) has verified that Syria has dismantled and destroyed all the chemical weapon production and mixing facilities. Bashar Al Assad’s regime has therefore met a key deadline in the chemical disarmament agreement.

According to the documents received by Reuters, The watchdog visited 21 of the total 23 factories weapon sites before giving the verdict. The remaining two sites were deemed too dangerous but OPCW certified that all the relevant equipment had already been moved from those locations.

“The OPCW is satisfied it has verified, and seen destroyed, all declared critical production/mixing/filling equipment from all 23 sites,” the document said.

This is a huge milestone Russian-American-brokered deal, which prevented a US attack on Syria. The conflict arose when Sarin was used in a deadly chemical attack on the outskirts of Damascus on 21st August. The US and its allies were adamant that the attack was carried out by Assad’s regime, a charge which the Syrian leader vehemently rejected.

Syria has met the November 1 deadline for phase 1 of the agreement. The second phase involves the complete disposal of chemical weapons possessed by Syria till mid-2014.
