RNA - "Ties with Tehran benefit the resistance front and the Palestinian cause and Iran's position on supporting the resistance is clear," Abu Zuhri was quoted as saying by the Palestinian SAMA news agency.
"Hamas is an alley of all sides which support Palestine, including Iran, and these ties have returned to normal in line with supporting the resistance project," he added.
Abu Zuhri said that the recent visit by a Hamas delegation to Tehran was in line with supporting the resistance and political consultations on political issues related to Palestine and other regional developments.
A high-ranking Hamas delegation began a visit to Iran on Friday to inform Tehran about reconciliation efforts with rival Palestinian faction Fatah.
The group led by Deputy Head of Hamas political bureau Saleh al-Arouri will meet senior Iranian officials over the next several days.
The two Palestinians factions have agreed a landmark deal to end a decade-long split and are seeking to form a unity government along with other parties.
In relevant remarks on Saturday, Iranian Supreme Leader's top adviser for international affairs Ali Akbar Velayati praised Hamas for insisting on continued armed struggle against the Israeli occupation.
"We congratulate you for declaring that you will not set your weapons aside and for describing it as your redline," Velayati said in Tehran on Saturday.
Velayati underlined that he welcomes meeting with the resistance groups' officials, specially Hamas, on any occasion.
