What Is Yemen's 'All-Out War' Order Against the Houthis?

Yemeni President Rashad al-Alimi said Sunday he is ordering the start of military operations to retake all territory held by the Iran-backed Houthi movement, according to BBC News. "Today, I announce the start of military operations to retake the remaining territory of the republic and extend the authority of the state and its institutions across the entire national territory," al-Alimi said in a televised address from Riyadh, Saudi Arabia, the BBC reported.

What did al-Alimi actually announce?

Al-Alimi's government is internationally recognized but does not control Yemen's capital. He framed the operation as an effort to extend state authority across the country, not a narrower push on a single front. The BBC reports the statement was "expected" after the Houthis' offensive last month, which seized the national coastline, including the Bab al-Mandab Strait shipping lane.

What triggered the announcement?

The declaration follows an exchange of strikes between the Houthis and the Saudi-led coalition. Houthi military spokesman Yahya Saree said the group fired a ballistic missile and drone attack on Saudi national oil company Aramco sites in Riyadh and the Khurais area, calling the strikes a response to what he described as 50 Saudi-led coalition strikes within 12 hours, per the BBC. "Both operations successfully achieved their objectives," Saree said, adding the strikes "caus[ed] large fires at the targeted sites." Saudi Arabia has not commented on the claim, though it has previously dismissed some similar Houthi assertions, the BBC notes.

Who controls what on the ground?

Sanaa, held by the Houthis for more than a decade, has come under sustained government attack, and strikes have spread to the Saada region, the group's northern heartland, according to the BBC. Yet security sources cited by the broadcaster say the Houthis have continued to make gains elsewhere. The central battleground is Taiz, still held by the recognized government. On Sunday the Houthis cut the supply route linking Taiz to Aden, the government's interim capital, effectively encircling the city, three Yemeni military sources told AFP, as reported by the BBC.

Key figures

• 50 Saudi-led coalition strikes claimed by the Houthis in 12 hours before the Aramco attack
• More than a decade of Houthi control over Sanaa

"They've achieved the military objective of isolating Taiz from Aden, even if they haven't fully taken control of it," Farea Al-Muslimi, a research fellow at Chatham House, told AFP, per the BBC.

What role is Saudi Arabia playing?

The BBC reports al-Alimi was unlikely to have made the announcement without Saudi Arabia's approval, since the kingdom remains the government's key backer. Saudi Arabia has itself faced repeated Houthi attacks targeting its oil infrastructure.

Timeline of the escalation

• Last month: Houthi offensive seizes Yemen's coastline, including the Bab al-Mandab Strait.
• Oct. 3: Houthis claim a missile and drone strike on Aramco facilities in Riyadh and Khurais.
• Oct. 4 (Sunday): Houthis cut the Taiz-Aden supply route; al-Alimi announces the all-out operation in a televised address.

The BBC's reporting leaves open whether Saudi Arabia will confirm the Aramco strike or respond publicly to al-Alimi's declaration.
