The United Nations says Syria is on target to meet a deadline for destroying production equipment for its chemical weapons stockpile. Inspectors say they have been able to verify 21 of 23 chemical weapons sites, with the remaining two unreachable because they are located in a conflict zone. Syria is slated to destroy chemical production and mixing facilities by November 1, a key milestone in the U.N. Security Council deadline for the chemical program’s full destruction by June 30.
