Aden (South24 Center)

Damascus has confirmed ongoing military cooperation with Saudi Arabia, including training, consultations, and the exchange of expertise, amid reports that Riyadh and Syria have reached arrangements to deploy thousands of Syrian troops for military operations against the Houthis in Yemen. Syrian officials denied plans for a combat deployment, while Saudi Arabia has not publicly confirmed the reported arrangements.

Agence France-Presse (AFP) reported on Saturday (November 7), citing Yemeni military and government sources, that Saudi Arabia and Syria had agreed on arrangements to deploy up to 10,000 Syrian troops in stages to Saudi Arabia and Yemen for operations against the Houthis.

According to AFP, three Yemeni military sources and a defense official said hundreds of Syrian troops had already deployed on both sides of the Saudi-Yemeni border, with further reinforcements planned.

A source in Yemen's Presidential Leadership Council (PLC) told the agency that an initial deployment would involve approximately 3,000 Syrian troops, including officers and military specialists, to support military operations alongside Saudi-backed forces.

A senior official in Yemen's Ministry of Defense said the broader plan could eventually involve as many as 10,000 troops, while Saudi and Syrian technical teams were finalizing arrangements in Riyadh.

One Yemeni military source claimed that Syrian personnel already deployed on the Yemeni side of the border were directing drone operations against Houthi positions.

The reported arrangements were approved during Syrian President Ahmad Al-Sharaa's visit to Riyadh on Wednesday (November 4), according to the PLC source.

During the visit, Al-Sharaa and Saudi Crown Prince Mohammed bin Salman oversaw the signing of several bilateral agreements, including a defense cooperation agreement, as confirmed by the Saudi Press Agency.

However, the official announcement did not mention any arrangements for Syrian combat deployments to Yemen.

Separately, Reuters reported on Friday (November 6), citing two Syrian military sources and a senior US official, that Syria had sent a limited number of military personnel to Saudi Arabia in recent weeks to provide military advice and training.

The US official said Syrian advisers were helping train Saudi and Yemeni forces inside the kingdom. The report did not establish that Syrian personnel had entered Yemen or participated directly in combat operations.

In response to the deployment reports, a Syrian diplomatic source told the official Syrian Arab News Agency (SANA) on Saturday that claims about sending Syrian military forces to Yemen were entirely unfounded.

The source confirmed that existing military agreements with Saudi Arabia covered training, military consultations, capability development, and the exchange of expertise.

Saudi coordination visits to Syria are expected to begin in December, while cooperation could eventually develop into a mutual defense agreement or Syria's participation in the Makkah Joint Defence Agreement, the source added.

The Syrian official emphasized that Damascus remained focused on domestic security, reconstruction, and economic recovery.

Saudi Arabia, Turkey, and Pakistan signed the Makkah Joint Defence Agreement on August 7, establishing a framework for collective defense cooperation amid growing regional security threats.

Syrian Foreign Minister Asaad Al-Shaibani said on October 31 that Damascus was considering joining the agreement as part of broader regional security arrangements.

The conflicting reports come amid escalating hostilities between Saudi Arabia and the Houthis, who have intensified missile and drone attacks against Saudi airports, oil facilities, and military installations since July, with a sharp escalation in October.

Riyadh has sought additional defensive and military assistance from regional and international partners as operations against the Houthis continue across several fronts in Yemen.

In an analysis published on October 15, titled "From a Battle to Restore the State to a Sectarian War: The Risks of Deploying Syrian Forces to Yemen," South24 Center Executive Director Farida Ahmed examined the potential consequences of involving Syrian troops in the conflict.

The analysis argued that deploying foreign fighters with jihadist backgrounds could introduce a sectarian dimension into the war, potentially providing the Houthis with new opportunities for political and ideological mobilization.

It also warned of possible long-term security repercussions for South Yemen, particularly if foreign fighters linked to extremist factions became established in areas where Southern Forces have conducted extensive operations against Al-Qaeda in the Arabian Peninsula (AQAP) and ISIS.

The analysis emphasized the importance of strengthening local anti-Houthi forces, addressing divisions among government-aligned formations, and supporting Southern military capabilities rather than relying on foreign ground forces.

The prospect of Syrian military involvement raises questions about Saudi Arabia's expanding regional defense partnerships and the future direction of its campaign against the Houthis.

No official Saudi announcement has confirmed a Syrian combat deployment to Yemen, while the reported troop numbers, deployment locations, and operational roles remain independently unverified and are disputed by Damascus.
