While there are no consequences for missing the deadline, the group's failure to meet it underscores the ambitious timeline as well as the risks its inspectors face in carrying out their mission in the middle of Syria's civil war.
The OPCW did not say who was responsible for the security problems, but Uzumcu has said in the past that temporary cease-fires may have to be negotiated between rebels and forces loyal to President Bashar Assad to reach some sites.
The two sites appear to be in rebel-held or contested areas. At least one location is believed to be the town of al-Safira, which experts say is home to a production facility as well as storage sites. It has been engulfed by fighting for months, and many rebels in the area are from al-Qaida-linked groups.
U.N. Secretary-General Ban Ki-moon said in a seven-page letter to the Security Council, also obtained by AP, that the joint OPCW-U.N. mission is constantly reviewing security at the two locations “with the intention of visiting them as soon as conditions permit.”
The mission faces a string of target dates for specific tasks as it aims to achieve the overall goal of ridding Syria of its chemical stockpile by mid-2014. The next target is Nov. 1 when Syria is to complete the “functional destruction” of all equipment to produce chemical weapons, aimed at ensuring that Syria can no longer make new chemical weapons.
