Benjamin Netanyahu visited a hospital in the Golan Heights where Israeli doctors treat Syrians wounded in the civil war raging across the border.
Netanyahu said the Syrians' treatment represents "the true face of Israel." He said Iran is arming the Syrian regime and the wounded are the "the true face of Iran."
Iran is a close ally of the Syrian government and has sent fighters to Syria.
Although Israel and Syria are enemies, Israel provides medical treatment for wounded Syrians that reach its border.
Israel says Iran is seeking nuclear weapons, which Iran denies.
