Support for Palestinian groups has been one of the unchanging principles of the Islamic Republic since the 1979 revolution. Iran’s support for various Palestinian groups and figures has ebbed and flowed with the changing political realities of the region but has never dropped off completely. In his latest speech, Supreme Leader Ayatollah Ali Khamenei, who has the final say on the country’s foreign policy, said that even with a nuclear deal, Iran’s support of “resistance groups” would continue.

However, it is no secret by now that since the unrest in Syria began in 2011, relations between Hamas and Iran have deteriorated. Iran pushed the Sunni militant group to politically back its ally President Bashar al-Assad, while Hamas was on the defensive, denying accusations of supporting Assad’s armed opposition. Relations between Hamas and Iran have not recovered since Hamas leader Khaled Meshaal left his longtime base in Damascus in 2012 for Qatar, one of the main sponsors of Assad’s armed opposition.

There were rumors in the Iranian media that Meshaal would visit Iran and meet with Khamenei, but those rumors failed to materialize. It is understandable then that when Hamas leaders, including Meshaal, visited Saudi Arabia and met with King Salman bin Abdul-Aziz Al Saud on July 18, the Iranian reaction was swift.

Perhaps the strongest criticism came from Reformist Ghanoun newspaper in an article by Saman Saberian, “Hamas: Bank account in Tehran, stronghold in Riyadh.” Saberian wrote that Hamas’ turn to Saudi Arabia cannot be viewed as merely seeking Saudi funding and help because in the latest war, “The Saudis helped Tel Aviv the most and the only support they gave to Gaza was coffins for the martyrs.”
