Saudi Arabia has said its national security is a “red line” it would defend, hours after a coalition it leads struck vehicles and cargo in Yemen that it said has been supplied by a foreign military to separatists in that country’s south.
The coalition’s “limited military operation” at Mukalla port in Yemen came days after it warned the separatist Southern Transitional Council (STC) group against taking military action in Hadramout province.

Yemen’s Saudi-backed presidential council has named the United Arab Emirates as the country that supplied the assistance to the STC that was targeted in the coalition’s strike.
The Saudi Ministry of Foreign Affairs said in a statement on Tuesday that it hopes the UAE will take the necessary steps to preserve bilateral relations between Gulf Arab nations.
Coalition spokesperson Turki al-Malki said two ships entered Mukalla port on Saturday and Sunday without coalition authorisation, disabled their tracking systems, and unloaded large quantities of weapons and combat vehicles “to support” the STC.
The Saudi-backed head of Yemen’s presidential council, Rashad al-Alimi, said on Tuesday after the air strike that all forces of the UAE must leave Yemen within 24 hours.

In a televised address, al-Alimi framed the move as a sovereign requirement and renewed his praise for Saudi Arabia and the coalition for their support. The Yemeni leader also cancelled the joint defence agreement with the UAE, announced a 72-hour air, land and sea blockade, and declared a state of emergency for 90 days.
“Given the danger and escalation posed by these weapons … the coalition air forces carried out a limited military operation this morning targeting weapons and combat vehicles that had been unloaded from the two ships at the port of al-Mukalla,” the official Saudi Press Agency (SPA) reported.
Two sources told the Reuters news agency that the strike specifically targeted the dock where the cargo had been unloaded. The coalition said there were no casualties or collateral damage and emphasised that the operation was conducted in accordance with international humanitarian law.
The strike comes amid heightened tensions following an offensive earlier this month by the STC against Yemeni government troops backed by the coalition.
Saudi Defence Minister Khalid bin Salman Al Saud posted on X that the STC troops should “peacefully hand over” two regional governorates to the government. Meanwhile, United States Secretary of State Marco Rubio called for “restraint and continued diplomacy, with a view to reaching a lasting solution”.
A divided Yemen
The UAE joined the Saudi-led military coalition to attempt to reverse the Houthi rebels takeover of Sanaa in 2014, but relations between the two countries have since become more complex, Sultan Barakat, professor in public policy at Hamad Bin Khalifa University, told Al Jazeera.
“Little by little, the UAE started the habit of undertaking foreign policy and independent decisions in Yemen without going back to Saudi Arabia,” Barakat said. “This resulted to some extent in strengthening the position of the southern separatists in Yemen.”
The STC was initially part of the Saudi-led coalition that intervened in Yemen in 2015 against the Houthis, but the group later pursued self-rule in southern Yemen. Since 2022, the STC, which has previously received assistance from the UAE, has controlled southern territories outside Houthi areas under a Saudi-backed power-sharing arrangement.
In recent weeks, however, the STC has swept through swaths of the country, expelling other government forces and their allies.
The head of the STC in the districts of Yemen’s recently seized Hadramout has signalled later on Tuesday that his forces have no intention of withdrawing from the region.
Mohammed Abdul Malik al-Zubaidi told Al Jazeera Arabic that the Saudi-led bombing this morning of the port of Mukalla was “a blatant attack on Hadramout and its people”.
He described the UAE as an “allied and friendly country” to the group working to take control of the southern parts of Yemen as a separate country, adding that it would be “unreasonable to reward them by leaving Hadramout”.
The STC official also tried to portray the internationally recognised government of Yemen as a “clear enemy” since it is allegedly “inciting Saudi Arabia against us”.
