Why Saudi Arabia is back at war in Yemen

Renewed fighting with the Iran-backed Houthis comes as tensions escalate across the Middle East A major escalation in Yemen has brought Saudi Arabia back into military confrontation with the Iran-backed Houthis, ending years of relative calm as tensions rise across the Middle East.

Much of the fighting has taken place along Yemen’s Red Sea coast and around the strategically important Bab el-Mandeb Strait, following major Houthi territorial gains and a Saudi-backed counteroffensive.

The waterway has become increasingly important as the US-Israeli war on Iran disrupts regional trade and energy routes, particularly through the Strait of Hormuz.

Who are the Houthis? The Houthis, formally known as Ansar Allah, are a Zaydi Shia armed and political movement that emerged in northern Yemen in the 1990s.

Their traditional stronghold is the mountainous province of Saada along the border with Saudi Arabia.

The movement emerged in opposition to Yemen’s central government and Saudi and US influence.

They now control much of northern and western Yemen, including areas where most of the country’s population lives.

The Houthis are backed by Iran and describe themselves as part of the Tehran-aligned “Axis of Resistance.” Over years of fighting, the group has developed an arsenal of ballistic and cruise missiles and drones capable of striking Saudi Arabia and ships in the Red Sea.

How did Yemen’s civil war begin? In 2014, the Houthis seized Sanaa and forced the internationally recognized Yemeni government from the capital.

Saudi Arabia intervened the following year at the head of a military coalition seeking to restore the government and counter Iran’s growing influence.

Years of fighting failed to dislodge the Houthis.

A UN-brokered truce in 2022 sharply reduced hostilities and cross-border attacks, and although it formally expired after six months, hostilities remained limited for several years.

Fighting resumed in July, when Yemeni government forces struck the runway at Sanaa airport to prevent an Iranian plane carrying a Houthi delegation from landing.

The delegation was returning from the funeral of Iranian Supreme Leader Ali Khamenei, who was killed in the opening US-Israeli strikes on the Islamic Republic at the end of February.
