Israel has opened its borders with Syria to provide medical treatment to Nusra Front and al-Qaida fighters wounded in the ongoing civil war. While Israel views al-Qaida and its allies as enemies, it is more concerned about the threat posed by Iran and its proxies. The fact that the Israel-Syria border area along the Golan Heights has remained quiet has sparked accusations that the Sunni Islamist alliance, which includes al-Qaida, is backed by Israel. Israel has denied actively aiding al-Qaida, but has made it clear that it will thwart Hezbollah's attempts to establish a foothold near the Golan frontier.
