U.S. Secretary of State Marco Rubio engaged in a crucial conversation with Saudi Foreign Minister Prince Faisal bin Farhan Al Saud on Tuesday, December 30, 2025, to discuss the intensifying conflict in Yemen. The readout from the State Department confirmed that the call focused on ongoing tensions in the war-torn nation and broader issues affecting regional security and stability. This high-level diplomatic engagement underscores the U.S.'s concern over the volatile situation in the Arabian Peninsula.
The discussions took place against a backdrop of significant developments, including the UAE's announcement of the end of its military presence in Yemen earlier on Tuesday. This decision, made at the UAE's discretion, was closely followed by reports of the Arab Coalition, led by Saudi Arabia, launching limited airstrikes targeting what it described as foreign military support at Mukalla port. The coalition alleged that two ships from the UAE port of Fujairah had entered Mukalla without authorization, disabling their tracking systems and unloading substantial quantities of weapons and combat vehicles intended for the Southern Transitional Council (STC).
These events have highlighted a deepening rift between Saudi Arabia and the UAE, two traditionally close allies. Saudi Arabia publicly accused the UAE of "highly dangerous" actions in Yemen, viewing the steps taken by Abu Dhabi as a threat to its national security. The UAE, in turn, categorically rejected these allegations, expressing surprise at the Saudi airstrikes and asserting that the vehicles were for Emirati forces with prior coordination.
The escalating tensions have prompted Yemen's Presidential Leadership Council chief, Rashad al-Alimi, to demand the withdrawal of UAE forces from Yemeni territory within 24 hours and announce the cancellation of a joint defense agreement with the UAE. Al-Alimi accused the UAE of directing forces to "rebel against the state authority" and militarily escalating the situation. Secretary Rubio had previously expressed concern over recent events in southeastern Yemen, urging restraint and continued diplomacy to achieve a lasting solution. He also acknowledged the diplomatic leadership of both Saudi Arabia and the UAE in supporting Yemen's sovereignty and regional security.
The ongoing instability in Yemen, coupled with the fracturing of the anti-Houthi coalition, presents significant challenges for regional peace and security. The situation could have broader implications for global oil markets, given the region's critical role in energy production and transit. Both Riyadh and Washington continue to emphasize the importance of intensifying coordination to support Yemen's political process and improve prospects for peace.
