Hamas is able to fire missiles into Israel because Tehran provided weapons technology to the militant group to defend itself against Israeli attacks, a senior Iranian official said Monday. Officials from Iran's powerful Revolutionary Guards have said in the past that Fajr-5 missiles are part of Hamas' Gaza Strip arsenal, whose technology has been supplied by Iran and produced locally without needing direct shipment.

Iran's supreme leader Ayatollah Ali Khamenei on Wednesday called for a referendum canvassing the Arabs and Jews that live in Israel in order to end the "Zionist state", but said until such a vote could be held, armed resistance was necessary. Khamenei and his predecessor the Ayatollah Rouhollah Khomeini have called repeatedly over the years for an end to the Jewish state, including through a referendum in the region, where Palestinians are in the majority.
