President Pezeshkian made the remarks in a telephone conversation with the newly-appointed Head of the Political Bureau of the Palestinian Islamic Resistance Movement (Hamas) Khalil al-Hayya on Wednesday, stressing that the issue of Palestine is the first issue of the Islamic World. He seized this opportunity to congratulate Khalil al-Hayya on his appointment as Hamas Political Office chief and expressed hope that he would succeed in serving the Palestinian people and the people of Gaza. Pezeshkian pointed out that Iran supports any decision, initiative, or measure adopted by Palestinian leaders during the ongoing negotiation process, reiterating Tehran’s continued backing for the Palestinian people. The president paid tribute to the Palestinian martyrs, particularly former Hamas leader Ismail Haniyeh, describing his assassination during a visit to Iran as a crime committed by the Israeli regime. Referring to the recent aggressions by the United States and Israeli regime against Iran, the president said the Palestinian issue remains a fundamental principle of Iran's foreign policy and continues to be regarded as the foremost issue of the Muslim world.
