Iran's foreign ministry spokesman on Tuesday refused to confirm or deny whether Iran had supplied Hamas and Palestinian Islamic Jihad with artillery rockets.Asked whether Iran had supplied its Fajr-5 rockets to Hamas, Rahmin Mehmanparast replied that it was "the duty of all nations, especially Islamic countries to take action to defend the oppressed people of Palestine, at a time when the Zionist regime is committing a crime," according to reports in Iran's state media.Asked where Hamas's Fajr-5 missiles were produced, Mehmanparast said: "The question of which country produces missiles should be asked of the military authorities [of that country]," according to Iran's ISNA news agency.
