WASHINGTON (AP) — According to the U.S. ambassador to the United Nations, reports of a poison gas attack in a rural village in Syria are so far "unsubstantiated."
Samantha Power tells ABC's "This Week" that the U.S. is trying to establish what happened before it considers a response.
Both sides in Syria's civil war are blaming each other for the alleged attack that reportedly injured scores of people on Friday. The reports come amid an ongoing international effort to rid the country of chemical weapons.
Online videos posted by rebel activists show men, women and children gasping for breath, their faces pale, at what appears to be a field hospital.
Opposition groups aren't saying what gas was used. State-run TV blames members of a rebel group with links to al-Qaida, saying they used chlorine gas to kill two people and injure more than 100.
