US State Department spokeswoman Jen Psaki: “We’ve been very clear about our concerns over regional instability caused by the crisis in Syria. …We continue to call upon all parties to avoid any action that would jeopardize the long-held ceasefire between Israel and Syria…There are a lot of complicated issues around the Golan Heights … but any effort to take this fight out of Syria into neighboring areas is of concern to us, just as the influx of foreign fighters is of concern to us as well,”
