This alarming escalation comes after a period of relative calm in such attacks, and is believed to be a response to the recent conflict between Hamas and Israel.

Iranian-backed militias had previously intensified their assaults following the Hamas attack on Israel, which took place on October 7. Taking credit for an attack in Syria on July 26, Iranian media outlet IRNA proclaimed, "Resistance groups have reportedly targeted a US military base with missiles in Deir Ezzor in eastern Syria." This incident further underscores Iran's increasingly aggressive tactics.

Earlier this year, in January, the Iranian-backed Kataib Hezbollah carried out an attack in Jordan that resulted in the deaths of three US soldiers. More recently, the group issued threats against both the US and Saudi Arabia, asserting the potential for further escalating attacks due to the ongoing conflict in Gaza. Simultaneously, the Houthis also escalated tensions by targeting Tel Aviv on July 19.

Now, Iran is effectively mobilizing its militias in Syria to launch more frequent assaults on US forces. This calculated move is part of Iran's larger strategic plan to exert maximum pressure on the US and potentially engage in a multi-front war against Israel.

According to pro-Iran media, "the resistance fighters [referring to Iranian-backed militias] targeted the US base in the Koniko gas field in Syria." These claims were echoed by Al Mayadeen and reiterated by IRNA. The report mentioned explosions being heard in nearby villages as a result of the missile attack. It also alleged that the US had retaliated.

Iran has also enlisted its militias in Iraq to initiate fresh attacks on US forces within the country. A recent attack on the Asad base on July 24 exemplifies Iran's directive to its proxies to resume targeting the US. IRNA highlighted that "regional resistance groups have repeatedly targeted US and Israeli interests in the region since the onset of the US-backed Israeli war on the Gaza Strip last October."

The motive behind Iran's return to attacks on the US in Iraq and Syria is attributed to the increased hostilities exhibited by the Houthi rebels against Israel, as well as Hezbollah's escalating actions. Additionally, there has been an uptick in activities by Iranian-backed groups targeting the Golan Heights, with Iran labeling all these entities as part of an "axis of resistance."

In an apparent coordination effort, the Iranian-backed groups in Iraq claimed to be engaging in joint attacks with the Houthis. Notably, the Iraqi militias recently asserted that they launched a drone attack on Eilat. Similarly, the Houthis have repeatedly threatened retaliation for Israeli airstrikes on Hodeidah, following their own attack on Tel Aviv.

Iran's decision to escalate comes amid a perceived distraction of the US administration with domestic political issues. Furthermore, it may be an attempt to exploit President Joe Biden's withdrawal from the presidential race and probe Vice-President Kamala Harris, who is now positioned as the likely Democratic candidate.

Efforts are being made by the US to de-escalate tensions through talks, potentially in Oman or other venues. Iran is aware of the ongoing hostage negotiations between Israel and Hamas and seeks to strengthen its position in the region before any potential ceasefire is reached.

The situation remains fluid and concerning, with Iran's increased reliance on proxy militias leading to a heightened risk for US forces in Syria and Iraq.
