France and the United Kingdom have both moved to deploy military assets to Saudi Arabia, deepening their defence ties with the kingdom as its conflict with the Houthis, an armed group also known as Ansar Allah (Arabic for Supporters of God), in Yemen escalates.

Paris last week said it had begun sending assets to Saudi Arabia as part of a previously announced agreement, after President Emmanuel Macron committed to deploying troops and air defence systems to help protect the Red Sea port city of Yanbu, which has come under attack from the Iran-backed Houthis.

The UK, for its part, on Tuesday announced plans to deploy fighter jets to help shield Saudi Arabia from Houthi attacks.

Both countries stressed that their support would be defensive.

Analysts say the European moves serve several geopolitical purposes: protecting Saudi oil exports that are important to European energy markets, shoring up their strategic alliance in the Gulf amid US reluctance to offer direct military assistance to Saudi Arabia, and strengthening deterrence against future Houthi attacks.

But the deployments also carry significant risks, many analysts say, potentially drawing the two European states more directly into the protracted Saudi-Houthi conflict.

“If insufficiently deterred, the Houthis may decide that the moment is ripe to test the resolve and resilience of Saudi Arabia’s defensive posture, and attempt to draw Saudi Arabia’s allies even further into the Yemen-Saudi confrontation,” Burcu Ozcelik, a senior research fellow for Middle East Security at the Royal United Services Institute (RUSI), told Al Jazeera.

‘Support during crisis’

The British and French military support measures come as Saudi Arabia faces a sustained Houthi missile and drone campaign against it, including targeting energy and transport infrastructure.

Houthi attacks targeting Saudi airports in Riyadh and Abha this month have killed 19 people and injured more than 300 others, according to the Saudi-led coalition spokesman Turki al-Maliki.

Addressing the UK’s stepped-up military support for Saudi Arabia, UK Defence Secretary Wes Streeting called recent Houthi attacks in Saudi Arabia “absolutely despicable”, specifically condemning the group’s targeting of Riyadh airport.

The UK Ministry of Defence said it would deploy Typhoon fighter jets to fly “defensive counter air missions” in Saudi Arabia, send UK military advisers to work with Saudi staff officers and provide an A400M transport aircraft to help move defence material within the kingdom.
