Supreme Leader Ali Khamenei and president-elect Masoud Pezeshkian held meetings with leaders of Iran-backed militant groups in Tehran including Hamas, Palestinian Islamic Jihad and the Houthis.

The meetings came before the swearing-in ceremony of Iranian president-elect Masoud Pezeshkian, highlighting Iran's ongoing support for the proxy militias.

During a separate meeting, Pezeshkian also expressed strong support for Hamas amid its war in Gaza, telling the group's political head Ismail Haniyeh, "We are certain that the resistance of the Palestinian people and fighters will lead to ultimate victory and the liberation of the land of Palestine."

Tehran has openly admitted to providing financial, logistical and training support to Hamas, praising the group's attacks on Israel on October 7 which killed 1,200 mostly civilians, while denying involvement in the specific operations. Hamas is now considered one of Iran's armed militant proxies in the region, alongside Lebanese Hezbollah.

In 2022, Haniyeh disclosed in an interview with Al Jazeera that his group had received $70 million in military aid from Iran. He noted, "We have rockets that are locally manufactured, but the long-range rockets came from abroad, from Iran, Syria, and others through Egypt."

The US State Department has previously estimated that Tehran's support for Palestinian terror groups, including Hamas, amounts to approximately $100 million annually.

Additionally, Pezeshkian met with Mohammed Abdul-Salam, the spokesman for Yemen's Houthi Ansarullah movement. He praised the group's recent actions against Israel and maritime navigation, remarking, "Your actions have clearly put pressure on the Zionist regime and its supporters." Pezeshkian also emphasized the necessity of collaboration among Islamic countries, stating, "We must work with Islamic countries to end the oppression of Muslims."

The Iran-backed Houthis have significantly disrupted the Red Sea, launching missile and drone attacks on commercial vessels. They claim to be acting in support of Palestinians, asserting that their targets are exclusively ships associated with Israel or its primary allies, the US and Britain. However, multiple ships without connections to Israel have targeted with dozens of non-Israeli hostages taken since November.

For several years, the clerical rulers in Iran have been the primary supporter of the Houthis, providing funding, arms, and training amid Yemen's civil war. This support has enabled the group to gain and maintain control over large parts of Yemen, despite facing a much stronger military coalition led by Saudi Arabia.

Naim Qassem, the Shia Lebanese cleric and deputy leader of Hezbollah, is also in Tehran to meet with Iranian officials and attend the oath-taking ceremony.

Since its establishment in 1979, the government in Iran has consistently positioned itself as a strong adversary of Israel and the United States. In the early 1980s, it founded the Lebanese Hezbollah as a proxy force to challenge Israel.

Currently on the brink of war with Israel, Hezbollah has been acting in allegiance with Hamas since October 8, sending 6,400 projectiles towards Israel's northern border in the worst tensions since 2006. Over 200,000 Israeli and Lebanese civilians have been displaced.

Over the past twenty years, Iran has expanded its influence by creating proxy groups in Iraq, Syria, Yemen, and the Palestinian territories. It also maintains networks in various other Middle Eastern, African, and Western nations.

Tehran provides Hezbollah, the largest and most powerful of its militias, with extensive financial aid estimated at hundreds of millions of dollars annually, in addition to advanced military equipment and training. Its missile arsenal is believed to be around 200,000. Hezbollah has been designated a terror group by countries including the US and UK.
