TEHRAN A two-day conference on the Palestinian Intifada opened here yesterday with an inaugural speech delivered by the Leader of the Islamic Revolution Ali Khamenei. Experts commented that the Leader's speech at the Tehran conference has determined the path of the struggle against the Zionist regime. Thirty-four parliamentary delegations comprising close to 300 political and religious officials from Arab and Islamic nations are expected to adopt a resolution in "full support of the Palestinian cause," and denounce Israel's "political repression," according to conference organizers.
