Yemen's Houthis have claimed carrying out a joint military operation with an Iranian-backed Iraqi militia, known as the Islamic Resistance in Iraq, to target four vessels in Israel's Haifa port. Houthi military spokesman Yahya Saree said in a televised statement on Sunday that the group fired drones at two cement tankers and two cargo ships at the port a day prior over noncompliance with a ban on entering "ports of occupied Palestine". Saree added that the group had also targeted a Shorthorn Express ship in the Mediterranean Sea using drones, and both operations "successfully achieved their goals". Israel's Channel 12 reported an explosion occurred in Haifa at dawn after an air defence missile was launched towards the sea without activating the sirens. Israel's military did not comment on the Houthi claim, but stated in a post on X that it had shot down a drone approaching the country overnight from the east.

Joseph Votel discusses tensions in the Middle East and how the Biden administration could respond to a drone attack that killed three U.S. soldiers, on'The Story.' An Iran-backed militant group in Iraq has promised to continue attacks on U.S. troops after three American soldiers were killed by a drone strike in Jordan on Sunday. In a statement released Friday, Harakat al-Nujaba, one of the strongest Iraqi militias, announced that it plans to continue military operations against U.S. forces while allied factions have backed off their attacks after the Biden administration said there will be retaliation. Akram al-Kaabi, the group's leader, called for an end to the Israeli military operations in Gaza and withdrawal of the "American occupation of Iraq," in a statement posted on X. The announcement comes after Kataib Hezbollah, another powerful Iranian-backed Iraqi militia, which is closely monitored by the U.S. government, said on Tuesday that it would "suspend military and security operations against the occupying forces" to avoid embarrassing the Iraqi government.

On Sunday, January 28, The Islamic Resistance in Iraq, an umbrella group that includes the militias Kataib Hezbollah and Harakat al-Nujaba among others, claimed responsibility for a drone attack that killed three US military personnel and injured 34 others in a base in northeastern Jordan, near the Syria border. In the media coverage of the attack, it was repeatedly mentioned that these militias have launched 165 attacks on US troops – 66 in Iraq and 98 in Syria – since October 2023. While it helps put the attack in context, this is a misleading figure. This conflict began much earlier than last October, and thus the total number of attacks the US has faced from these militias is actually much higher. Indeed, Sunday's drone attack was just the latest episode in an undeclared war between the United States and Iran-affiliated Iraqi Shia militias that has been raging across the region for more than five years. More than six years ago, in October 2017, in an article published on this very page, I predicted that US President Donald Trump's controversial decision to withdraw from the Joint Comprehensive Plan of Action, or the "Iran nuclear deal", would result in attacks by Iran-backed Iraqi militias on US forces in Iraq and across the region.

Gen. Qassem Soleimani was killed in a U.S. drone strike in Iraq, the Tehran-backed Lebanese organization Hezbollah urgently met with Iraqi militia leaders, seeking to unite them in the face of a huge void left by their powerful mentor's death, two sources with knowledge of the meetings said. The meetings were meant to coordinate the political efforts of Iraq's often-fractious militias, which lost not only Soleimani but also Abu Mahdi al-Muhandis, a unifying Iraqi paramilitary commander, in the Jan. 3 attack at Baghdad airport, the sources said. While offering few details, two additional sources in a pro-Iran regional alliance confirmed that Hezbollah, which is sanctioned as a terrorist group by the United States, has stepped in to help fill the void left by Soleimani in guiding the militias. All sources in this article spoke on condition of anonymity to address sensitive political activities rarely addressed in public. Officials with the governments of Iraq and Iran did not respond to requests for comment, nor did a spokesperson for the militia groups.
