State Department voices concern about deal to reduce Syria violence

WASHINGTON, May 4 (Reuters) - The U.S. State Department voiced concerns on Thursday about a deal brokered by Russia and Turkey to reduce violence in Syria, saying it was skeptical of Iran's involvement as a guarantor of the accord and Damascus' track record on previous agreements.

"We continue to have concerns about the Astana (Kazakhstan) agreement, including the involvement of Iran as a so-called 'guarantor,'" the State Department said in a statement. "Iran's activities in Syria have only contributed to the violence, not stopped it."
