BEIRUT (AP) -- An international human rights group says on the anniversary of the deadly chemical attack outside Damascus that "justice remains elusive" for the victims and their families.
In the early hours of Aug. 21, 2013, rockets carrying toxic chemical agents slammed into rebel-held suburbs of the Syrian capital. Hundreds were killed.
The Syrian opposition and its allies, including the United States, accuse Damascus of carrying out the attack. President Bashar Assad's government denies responsibility.
Human Rights Watch says no one has been held responsible for the attack, which was the most significant use of chemical weapons in decades.
The New York-based group's Nadim Houry says the victims will only have closure when those who ordered and executed the attacks "have been held to account and are behind bars."
