"Over the last 16 months, Israel has dealt a mighty blow to Iran's terror axis. Under the strong leadership of President (Donald) Trump and with your unflinching support, I have no doubt that we can and will finish the job," Netanyahu said.
Netanyahu said Iran had spent tens of billions of dollars to prop up the now-toppled regime of Syrian president Bashar al-Assad, as well as armed groups Hamas and Hezbollah.
During the sermon at a mosque in Tehran, Khamenei hailed Iran-backed armed group Hezbollah and Hamas, which are both fighting Israel and operate in Arabic-speaking Lebanon and the Gaza Strip, respectively.
