What is Iran’s ‘axis of resistance’? The groups across the Middle East supported by Tehran

While Hezbollah is the most powerful and well-armed of Iran’s proxies – the so-called “axis of resistance” spreads far and wide.

Iran’s Revolutionary Guards and its elite Quds Force give out millions of dollars in funding to arm and train militia groups throughout the Middle East to assert power in the region.

The axis is a key part of Iran’s foreign policy, which aims to destabilise “rivals” such as Israel and Saudi Arabia.

All of which is why the world is waiting to see how Iran responds to Israel attacking Hezbollah in Lebanon.

Here, Sky News looks at the different forces in countries throughout the Middle East that are backed by Tehran.

Hezbollah

Hezbollah has been of particular concern for Israel in recent weeks, with the Israeli military beginning a ground operation on Tuesday.

The group’s heavy presence in southern Lebanon, near the border with Israel, makes it of huge strategic importance to Tehran.

Last weekend, Hezbollah’s Shia political and military faction leader Hassan Nasrallah was killed in Israeli attacks in Beirut.

A passionate and fiery orator, Nasrallah was one of the most influential leaders within Iran’s “axis of resistance”. His death was seen as a big blow to all the groups involved.

Hamas and Palestinian groups

Iran also provides funding to Hamas, with analysts believing the group’s use of drones to help overwhelm Israel’s famous Iron Dome defence system in the 7 October attack was proof of Iranian involvement.

However, Tehran temporarily withdrew funding from Hamas when it came out in support of anti-Assad protesters in Syria during the civil war.

Its smaller rival, the Palestinian Islamic Jihad, also receives funding from Iran, as does the Popular Front for the Liberation of Palestine (PFLP) and the Democratic Front for the Liberation of Palestine (DFLP).

Sky’s military analyst Professor Michael Clarke said in October last year these smaller groups are “not very well organised”.

Syrian groups

Iran’s military, security and intelligence services have long assisted its allies in Syria to help prop up Bashar al Assad’s government there.

Strategically, as well as al Assad’s army, it has also backed several pro-government militia groups in case his regime falls.

Supported divisions include the Fatemiyoun Brigade, the Baqir Brigade, the Zainebiyoun Brigade, and Quwat al Ridha.

Yemen and the Houthis

Iran uses the Houthi rebels, one of three groups fighting for power in Yemen, as a “proxy force” to put pressure on its two main rivals in the region, Israel and Saudi Arabia.

Prof Clarke said last year the rebels are “prepared to make war on just about anybody” and suggested “it suits the Iranians to keep the Houthis going”.

A ballistic missile fired by the Houthis reached central Israel in September, with local officials saying parts of the missile fell on a train station and in an unpopulated “open area”.
