The Houthi anti-shipping attack campaign continues to achieve one of its desired effects of disrupting maritime traffic headed to Israel. Hong Kong-based shipping company Orient Overseas Container Line (OOCL) announced on December 17 that it would immediately stop shipping goods to and from Israel.[77] The company cited “operational issues” for the policy.[78] OOCL is the first global shipping company that CTP-ISW has observed to specifically halt operations to Israel since the Houthis began their campaign against international shipping around the Bab al Mandeb in November.[79] Global shipping giants, such as Mediterranean Shipping Company, CMA CGM, Maersk, and Hapag-Lloyd, previously announced that they would pause operations around the Red Sea but did not specify how it would affect their services to Israel.[80] Houthi spokesperson Mohammed Abdulsalam commended OOCL’s decision to stop sending ships to Israeli ports and falsely asserted that the Houthis are only attacking ships linked to Israel on December 17.[81] Several of the ships that the Houthis have attacked in recent days were en route to destinations outside of Israel, such as Saudi Arabia.

The Iranian connection is well known. This is from 2021:
Iran has provided the Houthis with weapons and technology for anti-tank guided missiles; sea mines; UAVs, such as the Qasef family; 122-millimeter Katyusha rockets; Misagh-2 man-portable air defense systems (MANPADS); RDX high explosives; ballistic and cruise missiles; and UMVs. One specific example is the Houthi use of Borkan-2H mobile, short-range ballistic missiles, which they have used to strike Riyadh and other targets in Saudi Arabia. A UN panel of experts concluded that the missiles were “a derived lighter version” of Iran's Qiam-1 missile and that Iran provided key missile parts to the Houthis. Iranian components were also integrated into Yemeni SA-2 surface-to-air missiles to construct the Qaher series of surface-to-surface missiles. The Houthis have also developed a modified version of the Iranian Quds-1 and Quds-2 cruise missiles, with Iranian assistance.

The Houthis claimed to have conducted two drone attacks targeting the Norwegian-owned, Cayman Islands-flagged Swan Atlantic tanker and Swiss-owned, Panama-flagged MSC Clara container ship in the Red Sea on December 18.[69] The Houthi Navy initially deployed unspecified “craft” with armed personnel to direct the ships to alter course before attacking them.[70] The Houthi military spokesperson claimed that the group conducted drone attacks on the two ships.[71] US officials stated, on the other hand, that multiple unspecified “projectiles” had been launched from Houthi-controlled territory in Yemen.[72] It is unclear what munitions the Houthis used to conduct the attacks at the time of writing. The USS Carney responded to the Atlantic's distress call.[73] Western media reported that the Atlantic was damaged in the attack.[74] The UK Maritime Trade Operations reported an explosion in the water near a vessel south of the port of Mokha in Yemen.[75] The Houthis have expanded their attacks on maritime traffic around the Red Sea to include all vessels traveling to Israel after having threatened to do so on December 9 and 12.[76]
The Houthi anti-shipping attack campaign continues to achieve one of its desired effects of disrupting Red Sea maritime traffic headed to Israel. The British petroleum company BP, Taiwanese shipping company Evergreen Line, and Belgian oil tanker company Euronav announced on December 18 that they will suspend shipping operations in the Red Sea.[77] Norwegian energy group Equinor similarly stated that it had rerouted an unspecified number of ships away from the Red Sea.[78] The above companies cited the “deteriorating security situation” in the area and concern for the “safety of ships and crew.” The Hong Kong-based shipping company Orient Overseas Container Line (OOCL) similarly announced on December 17 that it would immediately stop shipping goods to and from Israel.[79] Global shipping giants, such as Mediterranean Shipping Company, CMA CGM, Maersk, and Hapag-Lloyd, previously announced that they would pause operations around the Red Sea but did not specify how it would affect their services to Israel.[80]
The Jordanian armed forces clashed with Iran-backed militias attempting to smuggle weapons and drugs through the Jordan-Syria border on December 18. [86] Jordanian state media stated that this was the largest armed cross-border weapons and drug smuggling operation in recent years.[87] Several Jordanian army personnel and smugglers were injured or killed during the clash. The Jordanian army similarly announced that it had neutralized an unspecified number of drug smugglers attempting to smuggle Captagon into the country on December 12.[88] The Syrian regime and Iran-backed militias mass produce the drug in Syria and smuggle it through Jordan to the Gulf Arab states, generating billions of dollars of revenue for the malign actors.[89] Jordanian and Western officials have stated that Iran and LH have been behind the surge in drug and weapons smuggling from southern Syria into Jordan.[90] The Jordanian armed forces conducted air strikes on Iran-linked drug factories in southern Syria in May 2023.[91]
Jordanian officials have been concerned about Iranian threats to their security beyond drug and weapons smuggling.[92] The Jordanian Armed Forces shot down three drones that traveled into their airspace from Syria in August 2023, which Jordanian officials linked to Iran-backed militias in Syria.[93] Jordan also borders Iraq and the West Bank whose local governments and security institutions are infiltrated by Iran-backed militias that can then infiltrate Jordan from all directions. Some Western analysts have noted that Jordan is home to millions of displaced refugees from Iraq, Syria, and the West Bank which Iran can recruit for its militant groups.[94] Many of the Palestinian civil society organizations in Jordan are reportedly linked to Iran-sponsored groups.[95]
